This is what it ran , how much is left in it

Just an update finally got to the track I put an 8 3/4 rear end in the car a new torque converter 4000 stall upgraded the front Suspension went with a 750 perform carburetor and a new set of m/t slicks dam thing still runs 12.50 @ 103mph and a new holly blue pump I guess that’s all she has just wanted to give an update and say thanks for the help

can you post an actual time slip so we can see the incrementals?
Based on what its doing, sounds like The dyno the motor was on is mighty happy.
If it was making remotely close to 450 ish horse it would be well into the 11’s with way more mph.
