Which carb is best? Which air cleaner is best?
I have 2 questions, but i am looking for particular answers. First off, I have a q-jet off of a 1970 350 i want to use on my 350 i will be building. Any problems with these besides performance issues? If i dont use a q-jet, what is a good carb to use without over carbing. i am shooting for 300+ horsepower, but i dont want a gas guzzler. Also, i want to use an open element filter. I understand all the hot air problems but what are you guys opinions on these?

Fuel mileage is significantly better with warmer air entering the carburetor, but power would be way down.
The Carb Shop makes a very efficient and powerful quadrajet carb.

Here's a loaded question!
------------------
84 Camaro ZZ4 with HOT cam. 1.88 60' (12.98 @ 105MPH E.T.)
Recently Ported Heads, Installed Larger Race-Flo Valves and RPM Air Gap Intake (No new times)
Other Mods: You name it and I have probably changed it.

I had a Thermoquad on my 350, the small primaries gave good mileage but I could never get rid of the bog when the secondaries opened up.
