Perfect! You're just the guy I need to talk to!

Mine is a new 474 combo...so power unknown.

KRE HPs 380 CFM @ 750 lift. 74cc chamber

factory 455 block 4.211 bore - w/shrouding notches

4.25 stroke eagle crank

estimated compression ratio 11.2 to 11.5

comp cams solid roller 760 lift - 108 separation - 271/278 @.050 - installed at 104

Matched Gutsram with 2 660s

3300 pound early Firebird w th400 w/trans brake, Coan 5-5500 converter and 3.73

9x28.5 bias ply slicks with your basic Calvert suspension, bars, shocks and split monos, Global West Del-A-Lum low friction bushings front and back....stock shock mountings...no anti roll bar and running shackles..

What kind of power and ET/MPH were/are you making with your various 4150 flange Gutsram combos? ..Edit...just read your signature....NICE! Was the 9.77 with a Wenzler 1 or a Gutsram? What heads are you running?
