[ramsportman96]

The long wait is finally over, and the results are in on the 440 source 512 stroker kit. Stealth heads, 10.5 comp ratio ratio, Comp cams Xtreme Energy HI-LIFT 241/247 Hydraulic Flat Cam, 850 holley ultra. If any of you have always wondered if their kits make the advertised power, here it is. Let's hear your thoughts.

Nice! 
Makes me want to dyno my 512.  Gotta be close to that.  Thanks for posting!

Wish there was an engine dyno near SF Bay area.

Mine is a 383 stroked to 493, 10.75:1, with a lightweight 440 source crank and Stealth CNC heads, Bullet 246/251 hyd roller cam .612 lift w/1.6 rockers, Comp cams solid rollers, Brawler 1050 carb on Torker 383 manifold, and 2" headers.  Not yet installed.  Output wil be a mystery.

Still climbing, 600 by the look of it. I would limit to 5500 as well though with a hydraulic. Very nice numbers.

Very nice!
I also am heading in the direction of building a 512 440 source kit. I was thinking of a Lunati cam rather than Comp, but other than that I have the same heads and carb (proform) cfm. @Chryco Psycho is going to tell you that the carb is toooo small.
Was there any work done to the stealth heads? Mine are factory with Lunati springs.

Give them a call. They have chassis Dyno. Located in SSF. I am sure there should be others. https://www.ditosmotors.com/Auto-Repair
