93 cobra question

With that setup tuned correctly you should see between 450-500rwhp and around 425-475rwtq. Without an intercooler it isn't recommended you run much more boost or you can install a water/methanol kit to cool your intake charge and allow more boost/timing while fighting detonation. I imagine you're running a stock block so you're hindered by only 10 headbolts being only 7/16" apiece, not the best setup for holding head gaskets. If you at least use head studs rather than bolts they will help. Also, are you seeing 8lbs boost on your gauge or is it an 8lb pulley on the vortech? Having 8.5:1 comp will reduce your actual boost level but will allow you to run more timing and/or boost safely. I run a 17lb pulley on my procharger with 8.2:1 (roughly) comp and I see about 13lbs at the manifold with stock style heads and 7/16" head studs. Careful though, stock blocks do not like to see over 450-550hp. Your setup looks to be strong, but the block seems to be your weakest link, I tore the front half off my last block.
