Kits for350 chev in jeep? How? Where? HELP!!!

[cherokee_guy82]

Had a friend raving about putting a 350 chevy engine into a jeep wrangler years ago and he has since moved and I have lost contact with him. I would like to know if the engine and transmission bolt pattern and the engine match up or does the bell housing have to be adapted to the engine with a kit? If it does, what does it include and where can it be purchased from??? Any ideas on the possibility of putting a 4.3 chevy into a cherokee??? patterns and such are same as 350 and the engine mounts are similar. I know that the main systems will have to be switched but can the engine be put in in place of a bad 4.0?

save yourself the money and have a shop rebuild you 4.0 with the crank out of a 4.2 (from salvage yard) also use the cam from a 4.0 ho and the injectors from a ford 5.0 in the end you have about 1300.00 spent and a new engine thats now a 4.6 ltr with the torque of a tractor... (v8 torque at low end)
remember more power means more things break so do yourself a favor and upgrade the rest of the drivetrain (tranny rebuild with HD parts, stronger axles, so on and so forth

if you want to learn more look around for an article. its been done by jeep owners all over "4.0 stroker"

Go for the 350 transplant. As one poster put it, you will need to beef up your rear end (solid axles if you have a AMC 20) and U joints are the first to let loose under the increased tourque. The np242 transfer case and tranny should handle the extra power. One poster was telling you to rebuild your engine, change crank, cam and so forth. If you do all that you will still need to beef up your drive train. That's cool for keeping the great inline 6 engine and also for the emission control issues. If you can do it, I would opt for a 350 4 bolt main, bored .30 over, 9:1 compression pistons, a torque cam, high rise manifold, 650cfm carb, headers and a FLEX FAN to move the air under the hood and out of the engine compartment (clutch and electric will cause coolant temps above 220 degrees).

I installed the above in my jeep CJ-7 about 10 years ago. With 3.50:1 gears and 33" mudders, it's a 120+mph boogie machine. Lots of low end tourque and a power curve that comes on about 1,800 rpm and is good up to 5,200rpm.

I now have about 225,000 miles on the Cj-7 and 95,000 on the chevy engine. After the solid axles and larger u-joints it really has been a dependable runner. Gas milage is about 12 - 16 mpg, (depending on what I'm doing with it).

Emission control issues can be a pain in the ass for some states. In wisconsion and Ill, you must meet the emissions of the year of the engine installed. My 350 was a 1972, camaro, so my emissions had to meet that years emissions.

Be sure to check your local laws for emission controls and what you can and cannot do in you state. Keep all receipts for all and any work that was done to the engine. Illionis, required that I prove who did the work and what year the engine was.

Good luck

I did all this myself for under $2,500.00
