From what Ive seen with guys spraying big shots on the stock bottom end,theyre more concerned with track times than HP ratings.
Ive seen a few in the mid 9s stock shortblock with 300 shot if that gives you an idea.
Just figure 420rwhp on motor and add a 300 shot,so maybe high 6xxrwhp?

I dont really think there is such a thing as a horsepower record, on most dynos you can fool around with the calibration and get it to be whatever number you want it to be. I guess if you wanted highest hp, just look at the highest trap speed. As for ET, i believe its 9.62 or something like that, i could be wrong though.
I'll put my car on the rollers this afternoon, couple clicks and my stock bottom end will be up there with a top fuel dragster...shit i dont even need nitrous.
When my built motor was completed, I decided to see what my stock motor, with cam could do. It made 740rwhp through a glide, 9". It did this 2-3 times. We loaded it up to see what it would do at the track. During the burnout, the motor locked up...lol.
