That's my GMC - yes that cam I had ground to bigblock V6;s specs - engine really wakes at about 2500 rpm and from there on it's pretty strong with a Powerglide behind it. Engine started life as a 351E - installed new 379 pistons with custom made longer rods - Holley 500 carb - exhaust system is 2 1/4" with H pipe and Flowmaster mufflers. Old girl turns lots of heads even before they see me. Thanks, Cliff

Glad to hear the cam worked out good in your V6. Old BarryGMC:poop: heard about my custom cam specs and was spreading a rumor that those were just stock cam specs

Sounds like a lot of overlap. Is there enough vacuum for power brakes?
How does it transition from idle circuit. With the limited RPM range of the V6 are there real gains . I am just asking. Dave. Sure sounds cool!
