greetings everyone

My car is: fox mustang

5.3 form 2008 silverado
2500 precision stall
1 3/4 headers
2 1/2 exhaust X pipe, magnaflows
truck intake
243 heads milled .050 to get 11:1 compression

A friend got a regrind he never used it only says 228 intake 230 exhaust 114
.500 lift on both, I plan to use it on a 150 wet shot

since we are at 5200 ft elevation I feel 298 hp on locked converter seems fine, but power is peaking at 6200 rpm and keeps to 6400 ( 25 hp lower). So I need a cam with .550 lift or more duration to keep HP up to 6500 rpm ? or nitrous will extend my powerband?

Thanks for your help

Sounds about the right power for the parts you have listed. Headers/ exhaust is small. Intake is for midrange, cam is small.

we have a ls6 intake aronund the shop... it would give just peak power or will it extend powerband?
exhaust and headers are not going to be changed sadly

thanks
