Advise for next move w/ my car
I have a 72 Nova weighs 2878 ,412 sbc brodix Track 1 heads,4.56 gears 10.5 x 29.5 tire . I don't know much about internals other than it's a roller cam, steel crank which doesn't help any in my decision making because of the unknown.
Here's the deal it has a powerglide w/ 5200 stall car runs 10.60 all day but i'm running out of motor about 2 cars from the end of the quarter. I'm crossing the line @7100-7200rpm i don't like running car at max every pass.Oh almost forgot it's a 10 bolt rearend
I know i can go to 4.11 gears but i don't want to slow the car down what other options do i have.
Can i go w/ a custom grind roller cam to turn up around 7300rpm or what
any ideas or opions welcome & appreciated.
