Help with SBC cam selection
I got a '78 chevy k10 4x4 4 speed 31" tires and 3.73 gears I'm currently building a 400 sbc to drop in it, it will be stock bore with stock dish pistons, 062 vortec heads with steamholes drilled, and headers I was wondering what would be a good cam for this engine,I'd like a cam with a lobe at idle to, I'll be using it for towing cars and stuff every now and again and the truck hardly ever revs over 3,000 rpmsLast edited by 1978chevy; 02-11-2012 at 05:10 PM.
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
