I'm just curious. My dad grew up on Holleys (built/tuned a few way back when), so that's his stance. The Edelbrock (1405) I have has worked well for me both on the 305 and 350 it's been on, no driveability/idle issues, etc., and it's gotten halfway decent mileage. If it's any help, it's a street motor that sees basically no strip time. I don't really have a lot of tuning/troubleshooting experience yet, so I'm kind of middle of the road so far.
