Those same people claim IF I use a 871 blower I will not have heating issues. I clearly realize I WILL NEVER get this to hook up due to being so light nor will I ever use all the power. I just think polished superchargers look killer on early Fords. If running a 871 on my BBC what size of manifold referenced carbs should I be running? I am aware I need to be running 8 to 1 compression forged pistons. I would like to run a hydraulic roller cam with the blower, but do not have a clue as to what size or brand to go with. My motor is currently set up to run in the 2500 to 6500 power range. I am sure some of you knowledgeable guys could give me a HEADS UP as to which way to go. Thanks!
The heat problems people are talking about are more likely to accur when the 6-71 is "overdriven" 20% or more.This means you would have to run the engine on race gas or methanol.On pump gas with a 6-71 I doubt this would ever happen.
I would look for a mild street cam.I would run 220 to 230 at .050 and try to favor the exhaust by at least 6 degree's.I would also look at cams that run 110,112 lobe seperation.
