Does it have to be a 041 and 455 ?
In 1992 my '70 TA ran 12.815 at 105.5 mph with my numbers matching 400 engine.
Only engine modifications were those allowed by NMCA rules at the time.
Included no port work, 1.65 roller rockers, hyd cam and headers.
The cam was a Comp Magnum 380H with a similar 230 degrees intake duration.
Our NMCA weight break was at 3820 lbs. and I think we were about 60 lbs under.
3.90 gears, race tires, a B&M Hole shot converter and slapper bars.
