That extra pep and response is nice huh! I basically got the same setup with GM HEI. "Truckedup" hooked me up with a Holley 450 cfm w/ vac. sec. I like it. I like it a lot!
I was just offered an 8 lug Dana with approx. 3.55 gear (may be a bit high but, at least I can buy gears that don't cost $468!) from a '68 Chevy truck. Yeehaw! Get me to that freeway!
