If you don't mind telling. Where did you purchase your 92 90 set-up?

you will break 400 EASY... mine made 420rwhp with longtubes, much less aggressive cam than the one you will be using, stock 243 heads, and stock intake/tb

Very similar to my C5 mods and I was exactly at 400 RWHP---with an automatic---
An auto trans in a C5 had about a 20-22% drivetrain loss whereas a 6 speed manual only had a 10-12% drivetrain loss---Not so anymore on a C7 where the auto trans now is equal to or less in drivetrain loss
