86 project truck

[Sandia]

i just got a '86 pu and wanted to make a capable trail truck. not to fancy but not a piece. I have a '74 chevy 4x4(350/350/203)that has been rolled.i was thinking ti use that as a donor to buil the toy.I know the 203t-case is not the best but it is kinda stout. any ideas or suggestions. I wheel in New Mexico and do the rock thing, mud (if it rains), and explore the local trails and mountians. :Rockonman

if you use a 350 in a toy, you're going to have to put in a d60/14blt. you can probrably get by with 30 spline longs but i'm assuming you have big tires in mind if you want a 350. as for sugestions, get a doubler to mate the 203 to a 205. that would b cool. have fun

Heres an idea/suggestion:

Keep the 22RE
do a SAS + Lift.
add some lockers
bigger tires
gears
and dual case wont hurt either

And call it good.


Id rather have an 86 Toyota motor over a 76 Chevy any day. But hey thats just me.

[toy4x4]

^^^ definetly agree ^^^

keep the toy drivetrain. do a solid axle swap get some all pro or marlin springs. then get some lockers and a crossover setup. like he said dual cases would b another good idea.

DANG WHAT THEY SAID CHEVS SUCKY SUCKY.

in my opinion the only thing the chevy "donor" is good for is a really big paper weight.


so that said do what ramtoy said too do.

if u need hp to get threw mud try lower gears instead of a bigger motor.

also u wont be mud bogging with a v8 motor sitting on ifs supsension. and ur not gonna push mud with ifs.

so straight axle swap the toy and run low gears.

the reason i was going to use the chevy is because it is free and all the parts are there and are in good working order. i have a d60 with 4.10 sitting in my back yard and my buddie will sell me his front d60 .looking to run 35-36" tires and not to much lift.The carbed 22r in the toy is shot has a cracked timing chain cover,a rod knocking, and bad piston rings. The junk yards want 650-1200 bucks for a used motor.

[toy4x4]

i would still rebuild the 22r over swapping in a 350. swap in a toy straight axle for sure. comp guys are beating the living sh*t out of longs 30 splines with 42" tires, 4.3 chevy motors and very low gearing. not a single one has been broken except for a prototype that had a 4340 star instead of the 300m star they come with now. they will hold up to you're 36" tires and anything you can throw at them. for the rebuild, go to www.engnbldr.com.
i rebiult my 22r using his rebuild kit and it works great. he has great customer service and great prices. if you want some more power, get his 261c cam. 22r's are easy to rebuild you should have no problem.

[KToy]

i wouldnt take a non toy motor for free.

i wouldnt exchange a toy motor for a american made motor.

ud spend more money putting in the chev than rebuilding the toy motor in my opinion.

good luck.

I have had both toyota powered rigs as well as chevy powered rigs. I love my small block powered rig. I ran toyaxles with 39.5s and never broke anything with the exception of driveshaft bolts. If you are keepin to a small tire like 35s you would be plenty fine especially with longs. I would however do a solid axle though.... lots stronger then the ifs in my opinion.

I would keep the Toyota motor. Do a solid axle swap, lower gears, lockers, t-case gears, upgrade the front with longfields, and crossover steering. You can find a used 22R for cheap or rebuild it. The problem with putting a 350 in it is that you have to upgrade everything to stronger parts. You have to use chevy axles, tranny, t-case, and have driveshafts built. In 74 the 350's had really low compression and were pretty weak because of all the gas saving crap in the mid 70's. Plus the front and rear ends are likely 3:08 gears.

If you really want to run Chevy stuff why not just take the rolled parts truck and turn it into a trail rig? Take the cab off and make a truggy, rebuild the motor in the Toyota and use it as a daily driver.

They are all 300m stars, he had one of the first 4340 chromoly stars no promble sence with the 300m with 38s an 39.5. :beer:

thanks for the info. I would turn the chevy into a porpuse built trail rig but the frame is totally bent and twisted.the man who had given the truck was haulling some water drums and lost control and rolled. he made it out okay.i like the toyota engine and drivetrain(my daily is a taco.prerunner)but the other truck has everything and my fabrication skills arent that bad, better than my computer skills. lol. I was planing the sas no matter what i do ifs really sucks good if you like the whole race to baja deal. :Nerd:

I don't agree with having to change the axles just because you put a 350 in. I've been running Toy axles with a GN 3.8 for about 6 years. I went through several 700R4s, but the only damage to the axles was due to a bad pinion setup. I'm running quite a bit more HP and torque than a 70's truck 350. I'm also running stock Birfs on 35s. I have the turbo'd 3.8, 700R4, V6 t-case, and stock 4.10 gears. Rear V6 3rd with full Detroit, and front 4cyl 3rd with ARB. I don't run the extreme trails out here in Colorado, but the vehicle's been to Moab several times with no problems.

I do plan on upgrading to the new Longs when money allows though.

[bbagwell]

I have seen Toyota axles hold up to V-8's and take a lot of abuse. If I were going to put in a V-8 I would change the tranny, keep the t-case and run the stock axles. Once I started breaking Toyota axles I would upgrade to fullsize.

[Sandia]

If i do the motor and the trany/t-case i was going to use my dana 60 in back and try to find a dana 60(thats about all the money i want to spend,besides tires and diffs) to run in the front. in my old bronco 2 i ran a 302 and the stock axles(ford 7.5 welded and d28 open) and had no problems. So i would think the toyota axles would be stronger than the fords i had and stand up to the power. Driving with a light right foot would help alot too.

[toy4x4]

toy axles are alot stronger.

[bbagwell]

Toy axles are way stronger than those Ford axles.

[Sandia]

that front axle only had like a 6 inch ring gear.i am confident with a toy axle but much rather have dana 60's.

If you put a v8 in the toy you will need to beef the front springs for the extra weight. and the shoehorn it takes to fit one in there is a lot of work but when your done. you'll love the power. Mine only has a v6 in it and it is so much better than the stock toy engine. my toy was a dog even with gears.

I now can be going 65 and floor it and go as fast as I want to on the hyway and in the mud I can clear the tires with a romp of the pedal and when climbing I can heat the tires until their sticky. I have broken a few parts but that was totally my fault and extra heavy driving style. spinning first second and third and barking forth and fifth. with a toy g52 tranny. it willl break every time. even a w56 tranny will break I know I broke two of them. but with what your talking about sticking in there you should be strong enough.

here is one suggestion for you get a spare gas tank and mount it sideways behind the axle because with a 15 gallon tank and a v6 I was stopping all the time. now i have 30 gallons capacity and can atleast last the week.

also one more thing a dana60 with 39's has the same amount of housing clearance as a toy axle with 32's. at least I think that's what bud built told me so going big causes clearance issues as well.
