  • 4.7l I6!!!

    ive heard that you can turn a 4.0 into a 4.7 by utilizing a 4.2 crank and boring it over to make up the rest. how much power can i expect to get out of it after that. also, Cliffor Performance makes a head for the 4.0 that delivers 100hp more!!! can this fit on the motor after beeing bored out? If so that is a deadly combo, add an exhaust, intake, header, and maybe even a supercharger and you have some real power!!!

    please discuss.

    Jeezus, you can make a 4.7?? I bored my 4.2 out .030 and I think it's a 263 now..... but having a 4.7 would be sick!!! Think of the tourque! Now yer talking wheelies in first gear in low range..... :thumbs_up
