IMHO, i think the set-up u have is just fine :)...the 10-71 is a "whole" lot of blower for that c.i.
i would tune the chit out of it & go have fun...just my .02 cents

on pump gas. how much boost could i get away with on av gas?


Not sure of your static compression. but just a point of reference. My motors are from Merc racing, they are 502ci, 7.5-1 CR, 420 Mega blowers( about the same size as your 871), with big intercoolers. They run 10psi at full boost and run on 91 octane. With the motor set up right, you have a lot of hp still sitting on the table.

Depends on compression. To say the least gas is actually more powerful than alcohol. The window of burning up a motor on alcohol as compared to blown gas, alcohol can be out of tune more than gas and not gernade the motor.

I'd say NO more than 7

Be in the 5-7 range

3-4 if you run it wide open alot.

5-7 would be optimal
