I read it wrong I somehow seen "engine" dyno,..that's about rite my orange car made 415 and went 11.60s at 115 at 3900
While conservative it's not BS like some dyno's. Old dynojet 248 model that is stingy yet very realistic.
Here's buizila's cast ironed block 482. Made 702hp @ 6400 and 635tq @ 5000 @ 35* timing and 12.5:1. With the dry vacuum pump system and a different cam with more ramp it will easily make 750. Pull some timing out and don't be doing a bunch of holeshots every light and it's very streetable. A N/A 750+ cast high 9 sec GS street car very doable.
I drove my Stage 2 464 with 12.5 to the track for years. Ran 93 to get to track but never got on it. Then, when I got to track switched to small race fuel cell. Low tens at 3700 lbs.....

There's low 10's in it before making anymore slight changes to bring it up to the 750hp mark.
