Re: Please clear this up for me
us automatic trans guy's can only run so big of a cam or we wind up with no vacuum to run power brakes..
the bigger the cam ... the more stall speed you need in your automatic transmission converter..
the stall speed is built into the converter...
the bigger the cam the less vacuum your engine makes...
you need vacuum to run power brakes..and vacuum to run a/c flapper doors, heater flapper doors and such..
