big block pro comp heads

If your going to run 8th mile keep the 5:17. Quarter mile, for your cam, 4:30, 4:56 gears. The tallest and widest tire you can get under it. Eddy-Victor or M-1 work good, Carb should be around 850-950 cfm. 2 inch header. Like the guy before me said this combination likes a duration of 270-285 degrees at .050, lift in the .620 - .640 range.
But with 5:17 forget it. Your rpm level will yield short life. Your "modified" stock oiling system is all in at 7000 rpm.
