That was with the Wenzler 1. The Gutsram on my car was about .05 slower. I am running Std Port E heads that flow 345CFM.

My combo is 4.190 bore with a 4" stroke 990 Crank. Factory block, 4 bolt billet caps, Comp 274/280@ .050 with a .440 lobe on a 108LSA. 1.65 Crower Stainless Rockers. 2" Heddman Headers, TH400 with a 5200 PTC Converter and 3.90 gear. Full interior, 3.5" full exhaust and Stock Suspension. I have run 2- 600CFM Carters, 2-750 CFM Holleys, 2 -800CFM Edelbrock Carbs, but the car has run the fastest with 2 Carter Competition Series 9755S 750CFM carbs.
I shift around 7200/7400RPM.
It idles well and drives really good on the street. Most trips are around 20 to 40 miles to a cruise in or to take my 10yo daughter to lunch. Pretty docile on the street and highway about 65MPH.
Heres a video
