i have a 99 z28 6 spd with slp lid, ported MAf, fast 92/92, stage 2.5 5.3 heads, texas speed v2 tourquer, full comp cam valvetrain, lt headers, and cut out exhaust.

it put down 427 rwhp on a mustang dyno and ive had a couple people tell me i should be easily be making 450.

UDP might bump you up a tad. Maybe the dyno felt it was a Monday? I personally think those are really respectable #'s from a stock casting head, ported or otherwise. What's your comp ratio? Maybe go down a bit on the headgasket?

For your mods that's very respectable numbers....different dynos give different number.....take it to the track and get the numbers that matter

I have seen this combo make 450-460whp. on dynojets before. You are probably giving up 15-20hp. due to the mustang dyno. Do you have an auto or a M6? If you have an auto, your numbers are strong!

I went to the track for the first time this week and ran an 8.3 in the 1/8 on street tires and trapped at 93. My 60 ft were 2.2
