a rare breed its a 5.3 aluminum block stock 3.78 bore got it for a great price it came with stock pistons and rods no crank no heads im going to be aiming for 400+rwhp ill post pics up soon

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......

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.
