power Hey yall. Got a question. I have a 348 that has forged pistons, 242/246 cam with 621/614 lift. It also has TSP's stage 2.5 5.3 heads that were milled .040. So, with all bolt ons, the stock motor with ls6 intake, said cam and said heads made 454rwp. We pulled the block and did said work to the block and pistions. Put all bolt ons back on the new motor and also included a FAST 92/92 setup. The new setup is now down 40+ hp. How can this be? Would the forged pistions, which is all that we changed, rob me of that much power?
