Might have taken a light car, so what. The Butlers had some guy do it years ago with D ports;
Dan had a guy who could run 8.90s with his RAIVs a long time ago too.
But for some reason you want me to admit I am wrong.
Jim has been 9.39 with 96s. That a pump gas head.
8s are possible with smaller chamber, more CR and lighten the car up. Or real close to it.

Fact # 1: The Butlers DID have a guy who could give you a 262-265 cfm head (head after head). With that 265 cfm head the Butlers could run very good times (for that period), BUT THE BUTLERS ALSO RAN HIDDEN NOS ON THEIR ENGINES. So the Rodney/David Butler 265 cfm heads that ran in the 8s ran there because of several reasons. Spray, light weight, good cast iron heads, lots of track time.
Fact #2: The man has since passed on (years ago).
Aluminum Heads from Edelbrock was Jim Butler's solution to not having the cast iron employee's porting skills available.
