New hammer what will it run?

East coast mineshaft air can get really good.
Gonna stick with my mid 10.40’s in typical summer air. Maybe high 20’s low 30’s in mineshaft air.
I honestly don't see trick flow heads and a flat tappet making much if anything over 600 track backed up horsepower.
I figured my old W5 deal when i had it made an honest 640 horsepower. It went 9.80’s at 135@3350 pounds.
That was 13 to 1 with a 273@50 roller.
It later made more horsepower and went faster, but the above is an honest 640 on a well sorted 3350 pound car.
At 3170 it should do the above easy making anywhere close to 640. Just don't remotely see it.
