383 builds for drag car

Those State VI heads are pretty good and could lower a 330 pretty good. They would be great on a 383/400. I see these big blocks like big small blocks with that short stroke. The MP tips section has use of the Stage VI heads in the 10 second bracket tops section. They also suggest their porting templates, a mushroom lifter cam, tunnel ram and 5.12 gear with 14X32 inch rubber. Maybe a bit much? IDK….

I still and will always say, Run the best head you can afford. Port those Stage VI heads as well as possible. It’s worth the return on power no matter how fast you go.

W/4.56 gears, the tips section has that in the 11 second zone.
They suggest a single plane, 750, their mechanical 296/.557 cam @ a 11-1 compression ratio in a 3200 lbs (or less) vehicle weight.
They used to offer a OEM ported head and it’s suggest here as well but those of which you have are far better.

Also, FWIW, the MP tips section has the Stage VI in use for a first mention with a 440 in the 10 & 9.90 et top sections. With the .590 am mentioned in the 10 sec et.

The heads are capable on ether displacement.
