I'm building a 468" alcohol motor for my pro street car. Scat crank, Manley long rods and 13.5:1 forged pistons, Dart pro one aluminum heads, 700" lift Lunati roller cam, Barry Grant 1040 cfm alcohol carb, etc. What ring pack do you recommend for this build? Do I need any unique pieces in the build to work with the alcohol? Do you like gear drives or chains? Should I run a vacuum pump?

thanks,
roger
