thinking small block....

So I want a small block with a auto trans and ford 9 in rear. What's a good motor/auto trans set up? I tryed this once before in a cj but the trans was really long and wouldn't work. Any ideas?

depends on what you like best, I like chevys but that is just personal preference..350 turbo is shortest chevy...c4 for ford...9 inch is a good rear but a 1 ton is better

I was thinking a turbo 350 would fit. I wanna find a motor and trans combo. I have fund crate motors for a few grand. I dont want anything used. What one ton axles are good?

in a chevy basically anything 87 or earlier..I have 2 with full chevy running gears.1 has axles from a 87 chevy m1008 military.most of us call it a 1 ton but the military calls it a 1 1/4 ton..the other has 1/2 ton axles from a 69 gmc

I have a chevy tbi 350 mated to a 700r4..... works well and you keep overdrive...... Just make sure you find one with the tailshaft for 4wd... otherwise you're going to be pulling part the entire tranny to swap it out...

For crate motors, I'd get a ramjet 350 and turbo 350 trans, axles depend on what size tires you want to go to: 33-35":dana 44 or ford 8.8, 35-38": dana 60 or ford 9", 39"+: chevy 14 bolt is good

I'm thinking now I could pull the entire drive line out of a old pick up and just get them re built.... axles, motor, trans, maybe t case. What would be more cost effective ? Re building or buying all new

now you are thinking along the lines that I do...yep,use the t-case too as well as the driveshafts..just cut them down when you get to that point

Would my current tcase work or would you suggest getting a different one. What I'm thinking about doing is because my drive line in my jeep has only 117,000 miles is put it in a old cj or something. So I I think I might want to get all new stuff. Will I have to push my rear axle back??

my personal taste is doing a LS1 swap with a 4L80E for the tranny. wiring is pretty straight forward on that. just make sure you pull one that has 4wd and you may want to swap out for chevy axles. your gonna have to get the shafts retubed for them to fit...or if money isnt an option you can always get custom shafts built. IMO.

Swapping anything but a ford front is a pita and not worth the trouble. If you use later model gm stuff you use the ford axles anyway since gm quit making straight axles after 91

as I said earlier,I like the 350 turbos because they are the shortest chevy auto and I use the transfer case that comes with them for several reasons..since you are talking about buying a whole truck for the running gear,you will already have it..no expensive adapters will be needed..it will be at least as strong as the one in your jeep and probably much stronger..this transfer case will put your output for the front axle on the passenger side so a ford front axle won't work and if you buy a whole truck you have one already anyway..I can usually find an 87 or earlier chevy truck with a bad body or some mechanical problems dirt cheap..that way I can afford to rebuild everything in the drive train and still have a new vehicle pretty cheap..if you move your axle back then the angle on the driveshaft will be less and it will allow you to lift it more if desired..I have 1 cj7 at present with a full chevy running gear that the rear axle is in the stock location and it is fine but I only have it lifted enough to run 33's on it..if you deside to buy an adapter and use your transfer case off your jeep then you will need a ford front axle because the chunk will need to be on the drive side as it is now.I have just been working on old chevys since Moby Dick was a minnow so I know them a lot better and for that reason prefer them..

Ok thanks a lot! I'm really going to put everything you said into consideration. One more question... what would I need to do for motor mounts and trans mounts?

700r4 I believe was the first, it came out in the late 80's and most are overdrive since then..all overdrives will be longer than a 350 turbo..any of the transfer cases that were in chevys after they stopped using the solid axle will probably feed the front axle on the drivers side..this will probably include all the transfer cases that are attached to overdrive trannys

Out boarding the springs is a must on Chevy/dodge axle swaps. Also if its a 10 bolt your not gaining anything strength wise.

true on the spring mounts but it is not a big deal to do..my favorite of course is a 14 bolt.12 bolts are good but getting scarce..10 bolt is not my favorite for sure but probably a lot better than stock jeep.I see these farmers give them hell.My son put ( I think it was) 40 inch boggers about 17 or 18 inches wide on a 10 inch and was pretty hard on it with no problems..in my opinion regardless of the brand you go with,1 ton axles are the way to go..
