Not Ranked
I'd vote on the vac secondary. Light car, mech sec and dbl pumper, you'll just shock/overpower the rear tires that much easier. You can easily tune how fast/how soon the vac secondaries come in on the Avenger series Holleys by changing the springs in the vac module. Yeah, I've used mech sec/dbl pumpers, and they have their place.
I'm building an FE stroker to 455 cu.in., and I've got both 770 & 870 Avengers, I'll try both and see which works the best on mine.
I've also gave up on the Edel carb's; they're a good carb with a stock to mild cam, but once you get into a big cam, they're much harder to tune and get right, in my opinion (for whatever its worth?!?!?) compared to a Holley/Demon/etc.
