Oh I'm not arguing about valve issues,I had pontiacs myself,just that options were there,the superduty trans ams had the 12 bolt option as well.
Pontiac came out with the Judge in 70 and everybody though that was gonna put pontiac back into Super Stock racing.....My service manager raced one and simply wasn't competitive against the mopars an chev's. I was bracket racing which was dial in your own time.....when you got into the upper classes you were running against the heads up against the class record.
I ran formuls 1 for a couple of months with a tri power set up. I couldn't compete. I was running against a 10.36 time set by Dick Landy. I was a full 2 seconds off. I got put out in the first round every time. Bye Bye tri power ..... hello quadra Jet.
You sound like you raced Dime....What? I was NHRA
I was a much better street outlaw. Drags on Saturday....cruising the strip looking for a $20 race the other nights.
