HP on a 383 TPI
well here is the eventual plan....
383 TPI Heavily ported plenum, SLP siemese runners, eldelbrock base, Forged steel crank and pistons, ported DART iron eagle heads, big *** comp cam, (not sure exactly what yet), Vortec s-trim w/ somthin around 10 pounds of boost, then toping it off w/ 100 shot nitrous. Im also thinking of converting to SD and getting a functional ram air set up, doing this all mostly at one time so i only have to custumize the computer once. for exsuast, SLP headers, and a 4" exsuast
so far its only a dream....
whats your guys thoughts?

I'm not sure about what the hp would be with the supercharger and the nitrous, but the 383 you describe with using a decent cam and good heads would probably see around 420 in my opinion. However, you are really limiting yourself using the TPI setup. This car will never produce enough power to get past at the absolute most 5500. Since you plan on doins so much, add a superram to your package and step up not only to 6500, but a great power increase. I would say with that combo you could be staring at 450 maybe more and a nicer rev range. Add the other stuff and you could be looking at a 600-700 hp car. This could really be overkill for the trans and rear end, so be careful there too. Good luck.
