Default Another "What do you think it'll make?" thread

Ok, what do ya think it'll make?
388 cubes, AFR 195's, Edelbrock Pro-Flo EFI w/ 30# injectors, approx. 9.7:1, Crower hydraulic roller .526 int. .547 exh. 226/236 on 114*lobe center with 1 7/8" headers. Not that it'll make much difference, but the rods are 6", pistons are KB (polished crowns), the combustion chambers and exhaust ports are ceramic coated and the valve stems and guides are dry film lubricant coated. Any guesses? Just curious what you all think. My guess is high 400's. 480 or so.

475ish at the flywheel give or take, could be fortunate for close to 500 or unlucky and dwindle in 450ish, every motor goes different.

Good luck.

Thanks! It's good to see my expectaitions aren't that far off. A little spray or maybe some boost and thing should move along quite nicely!
