Its gonna take a decent sized cam and at least some type of head work to come close to 400rwhp....not impossible, but my ls6 heads 232 cam 6.0L hit 403 rwhp with a ls6 manifold......
nothing a little cash cant take care of i already have a set of 243s ill be doing the portwork myself, a custom grind cam, fast 92/92 setup that should get me there if not close to it :DQuote:

whats so rare about the aluminum 5.3L? didnt alot of gen 4 trucks come with that motor? just asking because i have a alum 5.3L in my 82 c10 and would be cool to know i have a rare motor. its stock but runs strong has 10:1 comp ratio 799 heads 30# injectors 87mm tb, its rated at 315hp and 338ft-lbs of torque. im very interested on how your build goes so keep us updated.
those blocks are hard to come by
