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......
