Ok guys clock my truck during this test (unofficially did it with a stop watch) and wanted to know what you all think if it is good for the truck or on the slow side. Did three runs each with improvements.
1. 14.99 Still cold engine not fully operating temp.
2. 14.83 Going up a slight hill
3. 12.53 my best time
1972 F250 390 .030 over (piston unknown) average of a 115 psi a cylinder (100 lowest 125 highest) edelbrock performance manifold, edelbrock 600 CFM Carb,(cam unknown) Standard FE heads,truck weight 5,800 lb, 4.10 gearing, 4 speed manual, with 33x12.5 R16.5 tires.
So what does everyone think The good the bad or the ugly (good,ok,bad) what are cheap ways to shorten this time?
