Last engine I ran I had 35 deg lead and when I tore it down the splayed mains were hammered. This engine I'm going to back down the lead to 32....
You need an 8. What does your pump flow? What kind of fuel pressure do you want?
I run an alky sbc, all iron, dry, 10-71 blown dragster as follows: 10-71, cam = .629/,669 280/290 @ .050, 112 lobe sep, 10.5 static CR, 180...

putting together 422 CI - 4.165 bore/3.875 stroke 10-71 blown sbc alcohol dragster. Boost = +/- 25 lbs. What would be a relatively safe static CR....
Is .250 enough distance between piston deck and first ring groove for blown sbc 25lb boost application? 355CI, 4.030 bore 3.48 stroke. Thank ITA
