GT Engine Combo - Page 2

1983 165/230 305 TBI
Cam is a little short as a stocker, good heads, no idea about the induction, but it uses a 2 hole TBI with 1.8 dia per hole. I'm sure it would work well on a SS type intake.
1989 220/235 305 PFI fits both stick and auto
I like the 1983 TBI

The 305 "dish" combos are not all that bad.

Actually, the O/P said "one of the slower GT classes", so I have been focusing my recommendations in that direction.

Mark,

I have an airflow test on just about everything, not sure who did the test but here is what they stated for TBI:

TBI 574.1 CFM complete, 584.7 CFM w/o injectors.
