How many amps needed from my alternator?
In the process of installing the Holley HP in my 1970 Buick GS. The car has a bb with alum heads, intake, big exhaust, solid roller cam, MSD 6AL box, no electric fans, big Magnafuel pump in a Tanks inc fuel tank.
Fuel pressure is holding fine until you really lean on it. It then drops to about 22lbs. I currently have the stock alt which puts out about 45 amps, and i am wondering if that could be my issue??
