Update I ended up using the OF Cam ground on 112 LSA with 1.65 rockers.
Motor is 463ci 11:1 compression with Kauffman 310CFM Heads. Runs Great!
I will be pulling the 4:10 gears out and swapping in 3:64
One question,
I was using 100 Octane when I first got it running and then tried 93 but
now getting some pinging at light throttle. 10 Degrees initial timing and
30 total. I have the vacuum advance hooked to full vacuum at the Holley
Carb, 950HP Street. Should it be on the ported vacuum source instead?
Thanks, Rich
