If you want to go chevy, it needs to be of the LT1 or LS series.

    The 4bt cummins has the same tranny bolt pattern as a 6bt. They are mated to GM tansmissions using an adapter plate made by cummins. This plate sells for about $700 used if you can find one. One thing alot of people dont like about the plate is that with the 6bt, it tilts the engine about 5 degrees to one side. Why, I dont know. I also dont know if it has the same effect on 4bt's but they are the ones that came with it from the factory.

    Put a 6.5L chevy diesel with a banks turbo kit in the jeep. You get good power and mileage and alot less cost. In fact, I know someone that is selling one.
    On the 8th day god created the Super Swamper TSL and said "go forth and kick ass"

    thanks, i dont really know too much about that engine. The only thing ive noticed is that parts are much easier to come by for the sbc than for the 360 but i may just not be looking in the right places.

    The 4bt has the same problem with the 5degree plate but they just make the tranny tilted in the conversions ive seen.

    I think pig pen needs the motor more than i do.

    If I got my hands on a 4bt I'd probably sell it and do some mod to pigpen to double its value.

    Yea there are less suppliers but anything you want is available. They just don't list many of them in the jegs and summit catalogs.

    yeah, just look in any hotrod mag and you can see where all the power is coming from. nobody runs smallblocks with aluminum heads and aftermarket parts anmore. all the cool kids run stock amc 360's. why, i was having lunch with zora arkus-duntov and dale earnhardt sr. last week and they both said they are switching to amc 360's this year...er something.
