Post Questions CJ-7 1985

I'm thinking of swaping my 258 for a AMC V8.
Possibly a 304 or a 360. (Can't get 401'ones here in Sweden)
I'm currently running a T-156 4 speed box
and the standard DANA 300 transfer box.

Will the 304/360 drop right in?
Will the T-156 cope with the stress?
I've read the postings stating that the 258 have better torque, but I'm only doing light Off-Road anyway, I WANT THE SOUND OF A V8!

Also, my steel doors are badly rusted, anyone knows of a supplier of repair parts for them?

Best bet is to either go ebay for replacement doors but you'll have huge freight from the US or take em to a panel beater and see what he can do.

I was also going to go 360 last year but when i saw the price of parts I nearly died... make SURE you know what it will cost just to get the engine running how you want it. And if its a rebuild - make sure you get it checked by a 3rd party - once you own it its too late.

Good luck and got any photos ?

Well, I have got an offer for a 304 and a 360, from a guy that that is presently running his Jeep CJ-5 with the 304 and a 3-speed manual, and he's thinking of converting
to the 360, but the 360 could also be sold "As is".
Price for either motor is 400 $.
I think I will go for the 304 motor although the 360 probably is the better motor with more power.
The 304 was after all a standard mount in the CJ line.
Pictures will be made during the engine swap, including describing text, for those who are interested.

No problem with my 304 !You'll have to locate motor mounts , and your t156 will be just fine .Don't forget about radiator upgrade and definetly run the fan shroud
good luck ,

I would reccomend the 360 over the 304. The 360 is a good motor, and the dimensions of the block are exactly the same as a 304, they have the same block. The 304 swap and 360 swap are identical. Heres a good writeup on a 360 swap.

I also have new fiberglass half doors from sale. They are steel horse and are gelcoated black. They do not accept windows and run $300 new, I will sell for $200, Also they are very light, so shipping wouldn't cost as much if you get steel half doors.

let us know how it goes

Found a 85 CJ7 tub in good shape with
minimal rust. The resto continues....

If you want to stick with AMC parts then get the 360. There is no substitute for cubic inches and it's the same basic block! Your T-176 with aluminum case is of marginal strength behind a strong running 304 or 360 so take it easy with either engine. Recommend a trans rebuild while you have it apart. I get sick of paying twice as much for performance parts and pulled my 304/T-15 drivetrain. Replaced it with a Chevy 350/NP435 combo. Easy swap, used readily available aftermarket and production parts to complete it.
Doors? I don't run no stinking doors.
