101 at 3710 shows 594 when i plug it in on Wallace. MPH is how horsepower is calculated. ET isnt much if any of a factor
As an example my old car went 110 at 3350 pounds, wasnt even set up for 1/8 racing. Using this same calculator, that shows 693 horsepower. My car, at that time, actually made 640. Nowhere remotely close to almost 700
So i think the 626 horsepower is ULTRA optimistic.
Probably more like 560, maybe 570.
throwing big numbers around sounds good, but MPH tells the real tale.
Having said all that, great job with the new heads, very mpressive for the relstively mild combo he has
I would suspect its going to likely take a roller and lots of squeeze to legit break 600 with those heads. Might be wrong, but i doubt it...lol
