97 tj with 4.2 stroker ??

Post by Jeepinjc »

New to the forum and strokers...

I have a friend that has a 97 Tj. The motor has some noise that is def a rod bearing. He found a 4.2L that has been stroked and bored .40. The specs to the motor are below. I am trying to determine if the 4.2 will bolt in and what issues I will face. Not sure about all the accessories mounting on the 4.2 block. Any insight and suggestions are welcome. I am good at building rigs but this is the first motor conversion.

Engine specs:

4.2L Base Block 258 block
Bored .040 over with Forged Dished Pistons
New Crank lightened, balanced, and polished
4.0 Head conversion

This is an awesome upgrade for anyone's jeep and will out perform most V8 conversion swaps
It is now a 264 cubic inch stroker with a 4.0 I6 head swap. Comes with a Header, intake manifold, injectors, fuel lines, throttle body, flywheel, clutch, ect. This is a direct swap in for any Jeep I6 and comes with everything.
