hello all.
I've got a relatively mild 446 in a 3700 pound coronet.
Some info:
-3:23 gear for now. May go to a 3:55 or a 3:73
-2800 stahl turbo action converter
-9.25:1 compression
-Ported 906 heads with 2.14 valves
-Crower solid flat cam 240ish @ .050 (gotta check the sheet for exact numbers) .620 lift
11" of vacuum at idle, in gear
-Holley street dominator intake blended to ported 906 heads.
I have an old AVS and have the typical AVS tuning issues I'm dealing with.
I'm considering a Holley vac secondary like the 3310 (can't find one without the stupid ford AT lockdown lever)
or a 750 DP.
Question is:
For a street driven hotrod, is a double pumper a foolish choice? I've fooled with the carter for over a year and have all the tuning do dads ever made. I don't want to out anymore money into the carter.
Is the 3310 available without the ford specific kickdown apparatus?
Is the 3310 pretty tunable without the secondary metering block and 4 corner idle screws or is it good money spent to buy the 750 with the block and 4 corner idle?
Thanks fellas
