305

[racer85304]

can u swap in a 305 motor to an ifs toyota pickup. i will be putting on a 4 inch lift. i just dont know if there is enough room. how much does the fire wall need to be moved if any one knows. i am going with the 305 because my neighbor wrecked his chevy pickup and is giving me the 305 for free. also does anybody have any links that have info on doing the swap from people who have done it.

If you're good enough you can put most anything in there. However, check Advance Adapters to see if they have anything for a 305 swap. I know they have stuff for 350, 3.8, and 4.3 swaps.

A 305 is basically the same block as a 350. Actually all older SBC share motor mounts, transmission bolt patterns and heads are interchangable. This applies to the 283, 302, 305, 327. 350 and 383(stroked 350) and I believe the 400 as well, but heads for the 400 may be different. The SBC shares the same tranny bolt pattern of the V6 block, the 3.8 and 4.3 so trannies are easily swapped.
I would'nt put a 305 in anything even if it was free. The motor is a total dog, probably the worst SBC made. The upside is you won't have to worry about the extra power breaking drivetrain parts, cause it's gutless.

[RedneckRockCrusher]

it will definetly work as was said before the block is almost the same as the 350 and thats what i just dropped in mine.

[racer85304]

thanks.

as far as the 305 being gutless it still must be 10 times better than the 22re that only makes 103 at the crank.

i just was not for sure about the swap on an ifs truck.

hey RedneckRockCrusher did u used to have efi or carb toyota motor. just wondering because i am going from efi to carb. do u have any problems about emissions. like the egr and other efi stuff like that.

[RedneckRockCrusher]

The 22re that was in there had a efi but i put a 4 banger on my 350. As for emissions had to change my converter and muffler. But it still hasn't been tested at inspection station yet. I go through next month. When I take it through inspection I will send you the results

i have a 305 in an 82 long bed s-10 its a mustang smoker. I had the motor in a 78 el camino . for a big boat that thing would get up and haul. I rebuilt it and dropped it in my little s truck. dropping it in my yota crossed my mind but thats my daily driver and my gas mileage. It is bored .030 over with a big cam a wieland intake stock crank stock heads a 600cfm edelbrock headers.

are you sure, i always thought a 350 was a 400 with 327 internals, thats why when you stroke it it becomes a 383. but that really doesnt matter, in his swap. im just trying to maybe learn something or remind sean, who ever is right.
but he is right about the 305 being a dog. i would much rather do a 302(chevy or ford), 350 or i think a 327 would be cool. i would think a ford 302 would be easyier because of the distributor being in the front you wouldnt have to make as many firewall mods.

[86taco]

I didnt have to make any firewall mods to my s-10. Some people move the whole motor/tranny foreward about 1".when I pulled the motor out of the el camino the splines inside the driveshaft were twisted about 1/8". needless to ssay I didnt use that one in the swap. About being gutless I beg to differ. Or my truck would beg to differ. I can do 70 in first and bark em into second. It hooks up like its on rails.

[L8sho2003]

I wouldn't go with the 305. Sure, you can modify it for more power, but why not start out with a 350 and be ahead of the game. You will spend enough money making the 305 competitive with the 350 that you might as well go ahead and buy a 350. Also, you can find 350 parts pretty much anywhere on the planet, and if rednecks ever make it into space you'll find parts on the moon too! The 305 in my experience weighs alot and drinks alot of gas for the amount of power it puts out in stock form. I would keep my 22re until I could find a better candidate for a swap. I consider the 305 the v8 equivalent to the 2.8 liter v6....both dogs.

;D iluvdirt & others, let's go to school on SBC's. The 283-350 sbc's are mostly the same. The bolt patterns for MM's & bellhousing are the same for the most part. Depending on the year motor/trans., the motor mounts could be different. The 400sbc is BASED on the 350 block. They got the 400ci. by using a different bore & stroke. The 400ci uses "siamesed" bores to get the max out of the deck along w/a longer throw on the crank. The 400ci heads ARE DIFFERENT!!! They have steam holes in them for the 400ci block. You CAN drill other heads to work on a 400ci. No steam holes = blown head gaskets!!! The 383 variation is a 350 crank in a 400 block w/a .30 overbore. HOMEWORK!!! Do your homework before trying ANY swap of this level. Later...
P.S. I just got a boat, anybody have a 305 I can use for an anchor?! ;D ;D ;D ;D

I just have a quick basic ?, what kinda money am I lookin at and time to swap a 350 in my 91 toyota pick up, dont incl. a engine or trans, like how much mods to I have to do, and does anyone else have this in there truck. only reason Im thinkin about doin this cause Im hearin alot of shit about my motor about blowin head gaskets, I just bought this for 900.00 bucks and It has blown head gaskets, im affraid to pull the motor out on a foriegn car cause I dont no if I could put it all back together right, its a 91 v6 4x4, ext. cab, short bed I will take some picks of it if I can find a way to put them on this website, talk to you all later

[Sean]

Towin, it's really going to depend on what year motor you choose to sawp in. Obviously a older carburated engine will be easier to swap in then a newer FI moter. Motor mounts are around a 100 bucks. Then you have to consider your tranny and transfer. If you go with a chevy transmission you would have to buy an adapter to mate it to your transfer case. The thing is you transfer case is not to great and if you swap the motor and trans you might as well swap the transfer as well.
Then you are looking at a custom cross member as well, which all and all would'nt be too hard to make yourself.
Right now I am considering a number of drivetrain swaps for my 90 V6.
Ford 302/T5/toy gear driven case = custom motor mounts and tranny to transfer adapter
Ford 302/T5/Dana 300 = same as above with cutom cross member
Chevy 350/sm465/np205 = motor mounts available, no adapters needed, custom cross member
chevy 350/nv4500/dana 300 = motor mounts available, tranny to transfer case adapter needed, custom cross member

Each set up has it's up side and down side. The toy gear driven case has available low gear sets as does the dana 300. The np205 does not to my knowledge.
You can run as many toy reduction units as you please, double cases or even triple. The 205 can be double with a np203 reduction box, but it takes it from the most affordable set up to almost the most expensive as well as the length really being more suited to a full size truck. The dana 300 can be double by a klune V, which are quite spendy, or a toy reduction box with proper adapters. Again more adapters means more money.
It really depends on your direction in your build up.

[cbowjones]

Sean can you go in to a little more detail about your v8 swaps you've listed. Like whether the transmission is an automatic or standard....that kind of stuff. Also, can you list the ups and downs to either swap. Thanks!

[towin]

so like can I hire someone to help me put my 91 v6 motor back in, I havnt messed with a foriegn engine yet so there is a lot of shit under that hood that I dont think I could remember to put back on, or is there a video or somthin, I havent takin it out yet either cause Im waiting to get some more money but I will be doin this in November some time, I was lookin at the Toyota auto parts.com and they had some heads for like $320 with a $250 core charge, or I could by the long block and heads already assem on the block for $2,459.00 but I couldnt afforrd that and be able to get it ruunin this year, remember I might be a tow truck driver but Im only gettin payed $8.50 an hr and have alot of bills...

All standards.
First option was a ford 302 bolted up to the world class T5 5 speed that came in the five litre mustang. Then use an adapter to bolt it too a stock 4cylinder gear driven toyota case. The 302 is physically a small motor with the distributor up front so fitament under the toyota hood is fairly easy. Also for me, I have one sitting in my garage waiting to go together.
The T5 I like less. It is a car transimission so it does not have a very low first gear. It does however have overdrive which is a bonus if you have enough power to use it.
I've actually reconsidered the T5 and will more likely use a np435 4 speed which has a granjny 1st gear
Then this combo gets bolted a stock 4cyl box. The advantage of the 4cylinder gear driven t-case is the gears can be swapped for much lower ones and it can be double using an adapter to put another 4cly reduction box in front of it. With low gears like 4.7:1 is one gear box and stock in the other you could get 4hi 4lo with 2.28:1 ratio, 4lo with 4.7:1 ratio or double low with a 10.7:1 combined ratio. The catch is that with a V8 such super low gearing is not as neccesary as with say a stock 22re although for crawling you still want at least 4:1 with an 8.
Another option for this engine tranny combo is a dana 300. Originally found is Jeeps and some Scouts the dana 300 is a stout gear driven box with a few advantages over the toyota box. Like the toy box the 300 can be upgraded with lower gear sets, although not as low as the Toyota. A couple things about the 300 make is special. One is twin stick ability. The ability to set up the transfer shifters so that you can engage front and rear drive seperately. This has several advantages from being able to limp off a trail in FWD to being able to run a front spool because you can disengage the front for turns while still staying in four lo.
The second advantage of the 300 is that it can be clocked. By this I mean an indexing ring can be made or purchased, so that the t-case can be turned to that it is tucked up tight under the frame rails for a flat underbelly. Most 300 adapters allow for clocking.
The next two combo's use a chevy motor. The major advantage is the availablity of bolt in or weld in motor mounts for the V6 trucks while for the ford small block the only motor mounts available are for the 4cylinder model. THe chevy small block has the distributor at the back of the motor means a body lift and some firewall hammering are usually requires. As well it physically larger then the 302 and is just a tighter fit.
The 350 is usually the stonger of the two motors powerwise, but the extra power in a toyota with stock axles may be a detrement more then an advantage. Of course 350's are probably the most common V8 ever, so finding a good one to build is usually as easy as hitting a wrecker to pick one up. Also being so popular the aftermarket is flooded with parts all for the best prices when compared to anthing else.
The sm 465 tranny is 4 speed used on chevy trucks from the early 70's to the mid to late 80's. Is has a granny first gear makingit great for crawling but lacks an overdrive gear. These tranny's are cheap and not to hard to find. The other tranny option I listed was the NV4500. A newer transmission that came into use in the early 90's in chevy trucks it has a granny first gear as well as an overdrive. It is also very strong as is the 465. The problem with the nv4500 is simply price and availability. New the are very expensive but available and form the boneyard they are a rarer find which will cost you some pretty pennies.
The 205 transfer is a New Process unit used in chevy's from the 70's through the 80's. It is gear driven and hence very stout but has a miserable low crawl ratio. Like mention it can be double with an adapter and s reduction box from a NP203, but this is neither cost effective or practiacal in a shorter wheelbased rig. The only reason I consider it an option is price and availabilty. It would make the swap cheaper and then I would change the T-case later using an adapter for the dana300 or atlas which is based on the dana 300.

Toyota had a recall on head gaskets of the 3.0 V6 and sent a notice out to lots of Toyota owners. You can have them replaced by a Toyota dealer for free. You may want to double check on that if you're not wanting to do a small block conversion right now. I agree, the V6 is a tough motor to work with, but you may not have to.

[carlos4x4sand]

K i got a Question? ok a couple, First off does anybody know what side is the 4wd drive shaft on a ford. Second If i were to swap in a V8, right now i have stock 4:10s, what is the lowest gear ratio i can go. What could i do to make the stock axle stronger?

[Sean]

I'm no ford 4x4 expert but I'm pretty sure EB's were driver side drop and so are all TBB trucks(80 and newer). So no I can't say I've ever seen one with a P.side drop.
The lowest gears usually reccommended for toy axles are 5.29's because the 5.71's are just to weak. Your stock 4.10 will be the strongest option. Also if you don't have a V6, upgradeing to a V6 diff will gain you a little strength. On the aftermarket there are cromoly shafts for the front and rear live axles, as well as improved birfs for the front and full floater kits for the rear. If you have an IFS front there are a couple companies making upgrades for them like downey and ORU.
