291 GM fuelie heads 2.050/1.60
Performer RPM air gap intake

Nice 60’

what weight?

 

Thanks! 3970 weight, I started with 25 PSI tire pressure, this produced the1.50 60, I really wanted a 1.4 60, and went back in the pits and put in 25.5, brought it up higher on the foot brake, it left with the wheels about 10 inches up, then blew the tires off upon returning to the ground, and unloaded the tires, then massive wheel hop, this broke the ring and pinion. In retrospect I should have lowered the tire pressure to 24 then brought it up higher on the foot brake, this might have got the 1.4s 60 foot, but no, DENIED. I was happy with the 7.04 though, my previous best was 7.22, suspension work brought it down to 7.04, I still haven't left with everything I have yet.
