Chassis dyno with my Vintage Trans-Am club Saturday,my first pull was 422 rwhp @ 6800 rpm.Pro Systems true 840 cfm carb (76/86 jetting) needed more rear jet so we bumped to 90's and ran 427 hp.Bumped them up further to 92's and retarded the timing a bit to 38 degrees and pulled 430.51 hp and 389.85 lb ft torque @ 5100 rpm...through the mufflers and air cleaner.We couldn't get a good air/fuel reading though the cut-outs so I ran them through the mufflers.

All of my engine specs are in my profile.

Mine's the Yellow one:
