What is the cfm rating on my stock carburator?
I don't want to go to 4bbl and manifold for cost reasons, so would upgrading to a higher cfm give me more power without affecting mileage too terribly?
I hope the math is right, but I have gotten 16 mpg towing 2 horses 5 years before my rebuild.
newly bored .030
rv cam
hv oil pump
HD everything
headers
dual flowmaster 2 1/4 exhaust
4 speed
Thanks,
