422 dyno fail

I have personally seen a 67.baracuda in stock form run low 12' with a 360/380.
The car was even a stick.
So as already stated something is drastically wrong with your car.
Plus 3400 lbs for an abody is super heavey.
My 70 340 4spd weighed 3240

Not super heavy for a 73-up in full street trim. Especially if have A/C.

I’ve digital scaled quite a few.

3250 is pretty good. Full interior, iron heads, intake, power steering, power brakes, disks, factory buckets???
