The 750 3310 vac secondary carb will give you the best of all worlds.
No 750 is not to much its vacuum actuated secondaries that you need to
stay with for the secondaries!

You should *at least* be using a 600 CFM rated carb - preferably a 650 CFM

Yet another $.02 worth from a proud owner of a 1970 Mach 1 351C featuring a
750 CFM Holley double pumper @
You didn't mention what type of driving you do. For around-town
cruising, a 750 vac. secondaries is OK, but is not the best carb for
all-out foot-to-the-floor fun.
I have a 72 Mach 1 Q-code and have had on it the following:
Vac. secondaries - 600, 700, 750
Dbl. pump -- 650, 750, 850
For drag racing, the 850 dbl pumper is just about right...actually, I
found 900 CFM is better.
Right now I'm running an Accel DFI system that flows about 1000 cfm,
but I have a large cam, lots of mods, and I drag race.

Hmmmm...I've been running Holley carbs for years, and never had any problems
with them, and never had one of them catch on fire. The most I've ever had
to do is "MAYBE" change the jets at the track because of a drastic weather
change. Anyway, if you had one catch on fire, more than likely your timing
was off, which caused it to backfire. That's the only way you can set a
Holley on fire.
Make your own from a 1" piece of aluminum, use the gaskets as the template
on each side of the block. No metal working tools? No problem, wood
working tools work well. Did this to get a Holley 4165 ( Chev carb ) onto
Not only works but looks great too.
