The GTO in my sig ran 13.50@105 with 2.93 gears, L88 converter in a Th400, performer intake and 850 mechanical demon, on 87 octane. No times with 3.42 gears, RPM, or ethanol.
The Formula hasnt made a full pass with the 467 yet. best 1/8 mile was a 7.40 using only 3rd gear and going easy on it. Hoping for 9s on the motor when its sorted out.
Previously the iron headed 455 in the Formula ran a best of 11.71@115 1/4 mile, 7.69@90 1/8th with 4.10 gears, and 7.51@95 1/8 with 3.42 gears. It was severely over geared with the 4.10 gears. Weight with the iron heads and steel hood was 3750 going down the track with 5 gallons of fuel. It was street driven and had 15in vacuum at idle, very mild mannered except for the race gas.

MSD 6AL with 52 degrees total timing. Yeah 52 total.

Th400
12 bolt from a 70 TA
The 72 455 HO Formula ran a best of 13.0 with the previous owner EnergyFx driving. What I know about it at that point was a TorkerII with 800 Edelbrock carb, Hooker super comps headers with mandrel bent 3" exhaust, 3000 stall in the Th400, and 3.70 gears, weight is around 3800lbs. It has a solid cam but I dont know the specs on it, if Ja sees this maybe he will chime in with whats all in it. I think it will go faster with a different intake, carb, a bit less gear like a 3.42, and I am thinking either a RAIV cam or a Crower hydraulic cam of similar size.
