Ged, what gears and convertor do you have? Also, what timing?

Definately need some more info. For comparison, my mild 360 Dart runs 14.2 on 3.23 gears. That said, when I screw up, it hits 15's!

Could be lack of fuel, what pump, fuel line size, have you got a fuel pressure gauge.

Had a Formula 400 a few years back, engine replaced with a GTO 389-six pack, run really strong, at 15.45 but 99mph!!! Still smoking one wheel, (no posi), through the line!!!!!

Will feel like stink on the street with only two barrels opening , maybe time to change the sec spring out.

Put a paper clip on the vac sec arm/rod , go cane it & see if the secs are opening , may need a lighter spring in there.

I hate vac sec carbs.

Who said that?

Only messin Ged , just windin em all up , was a topic a while ago

You dont have to sell your Firebird, just get it running better but without knowing your full combo it's hard to say how much quicker you can go.
With 470 ci, it should run at least 13's on road tyres.
