Carburator 101: Downleg vs Annular boosters on Holley and QFT carbs

[mcwho]

I wish there was a section on engine builds in here.

I have been doing research on which of these are best for Street Roadsters with a mild 33i cu in engine.

Specifically 302 Stroker @ 331 cu in, Edelbrock Performer Rpm Heads, RPM Air Gap intake, MSD Distributor, current carb is a Edelbrock Thunder 1806 AVS carb, 10-1 comp ratio, and Cam spec is: Hydraulic Roller 224 intake / 234 exhaust* @ 050 duration.* .542 / . 562 Valve Lift

For all the research I have read a few items such as Annular does not always work better than a downleg, I read that if you had a "cold intake" the Annular was better. I am building what I consider a daily street driver. I want reliability.

Looking at the Holley an Quick Fuel carbs I have come up with more opinions to stay with downleg. I also have read that the Annular Hardware takes about 30 cfm away from a carb because of the hardware restriction.

Based on what I have read so far, a QFT SS-650 is just a tad big for this engine but should work fine. This one had Mechanical Secondaried, Electric choke and downleg Boosers.

Commpens? Opinions?
