This may be a good application for a Q-jet. The small primaries will give the low RPM venturi velocity required to be responsive and meter fuel properly until the airflow demands increase to open the secondaries.
My first pontiac was a 60 over 350 with 670 heads, '68 iron intake, late 70s olds Q-jet, XE256 cam. Super comp headers and 3" exhaust. Stock converter, TH350 with redneck shift kit, 3.23 gears in a '67 Lemans. It would run low 14s. Wasn't a world beater but was fun for what it was. Would easily do the dairy queen burnout with 235/70-15 Firestones. Was a bit soft below 2200 RPM and had a slight lope. Maybe 8.9 compression with 76CC heads.
Late one night my GF at the time and her girlfriend "borrowed" the car and went terrorizing the good people of Jackson MS. I didn't wake up until I heard it chip 2nd down the street.
Another time I barely lost a top end run against a early '60 thunderbird. Car developed a vibration about 115 and I got out of it.
Good times.
