[QUOTE="swampratt, post: 4024803, member: 15054"] Checked cranking pressure on 1 cylinder with throttle open and the other 7 spark plugs in. 200 PSI. Makes me happy . That number or more has worked well for me when I need good stump pulling torque out of the hole. My 200" inline 6 ford had 210 my Corolla has 210 My 57 had 225 with the other cam I had and now is at 195 and down on low end grunt just a bit. At one time that engine had 245 PSI when I had it in my Nova. Ridiculous hole shot. I have been tweaking the tune today to eliminate a 2000-3000 RPM rolling bog when you nail the throttle. I have actually never experienced that and it could be the GM Iron intake. But more jet changes and tweaking will eventually tell me something. [/QUOTE]
