Some of you have probably seen my first post about build ideas for my fox. So far my goal is 500+hp and preferably keeping it a manual trans. I just got an offer on a 74 351w block with crank, rods, and pistons. Needs rebuild but hes asking only $150. Do you guys think this block is going to hold up? Like i said before i would like to make 500hp easy and a few of the guys i talked to said this block should be fine for that. I highly doubt i am going to use the stock internals anyway, i might get a stroker kit for a 393 or 408 or something.
