se428bandit, Thanks for the reminder for the head casting number. I was thinking that the combustion chamber volume was around 75-80 cc's to get anywhere close to 8.8:1 advertised compression. Is that the motor you have in your Ventura? I think the 068 cam would be great with some compression and 3.23 gears or higher.
At the Pure Stock Drags, Tom Miller's killer '69 350 HO Firebird ran 13.40's with an 067 cam (Turbo 400 car) and 4.10 gears. His HO only had 10.5:1 compression, so there was some HP left on the table. That car could run high 12's with 11:1 compression, 068 cam and factory 4.33 gears.
