carb. size
 

What size carb. should be used on a 434 sbc with dart heads,and 710 cam. I have been using a 750 holley running 6.10 in 1/8 mile, trying to get to 5.95 to 6.0

With good flowing heads, and 2" to 2 1/8" headers it should be able to support atleast a 950, possibly a 1050 double pumper carb.

At 2600# plus driver it runs 5.90's with M5 and 6.00 with M1 fuel. 60's are 1.25
