Steve are you running gas or alcohol, if you're running alcohol i think you have something left in it yet. When i first built my 377" motor, i put it in my friends 1850lb hardtail, we put 2 7/16" stacks on it, 456 gear, 16X33's, 5500 stall 1.76 PG. Leaving on a 4200 chip and shifting at 6800, it ran 5.16, with 1.14 60 ft. at Memphis. We pulled the high side chip out and ran 8.23 @ 158 in the qtr.
We ran the car at Super Chevy 2005 at Memphis and dialed 5.15 and broke out in the 3rd round with a 5.14. Never looked at the recall on the tach, but i'm sure it was zinging on the qtr. mile pass. i still have the motor in my Malibu but with a toilet bowl. Of course it don't run worth a crap in my car because it doesn't have enough torque for a 3200 lb car, best 6.52@102 and 10.59@125mph.
