    You should not have any problem with a 2 bolt and around 300hp.

    I agree, you shouldn't worry about the 2 bolts. and .030 over isn't that far of a bore, so you should be fine...

    i like the getting the 2 bolt blocks,all you have to do is find the four bolt main caps,factory or aftermarket caps and have the machine shop drill the block.and the aftermarket caps are stronger than the factory 4 bolt main caps!!

    82jimmy - you sure have a lot of plans for your k5. [​IMG] Did you find that 65 gallon tank you wanted so that that you can rob a bank and make a run for Mexico?[​IMG][​IMG][​IMG]

    no not yet...I work all summer for my grandpa and he owes me for working all summer...then I go to a convention and sell tshirts. Then I sell custom magnets for my uncle. so hopefully I can get all this stuff done in a year or so.

    Your 2 bolt shouldn't be a problem even upwards of 400 hp.

    Enjoy.

    I always heard that if the motor won't see anything above 6500 RPM, the 2 bolt style will be fine.

    I agree. I have pushed many 2 bolt blocks pretty hard when I was racing. never lost one because of that. other things!! I would get that rotation assembly balanced though. bad vibrations kill!!

    your right. I don't understand the jeep thing!
