For a descently built motor w/auto trans and street driven, which would give better all out performance/adjustablilty: Holley 650 double pumper or a Speed Demon 650? either way, I'm pertty sure I want to go with something that still has a manual choke for cold starts. It's for a small block with the Performer RPM cam/intake (port matched, ported/polished/milled factory heads w/perf. valve job, headers).
Any info would be appreciated.
