No graph, dyno was at engine guys shop, local.
Brian we started at 30 after 3 pulls , we checked lash, then tried 32, fell off more n dropped a lot after peak, so then we went to 28, and it was better, carrying it out n dropping not as much, 26 was the last pull #10, motor was plenty heat soaked at that time, we kept it at 170 water n 150 or so oil. There's more power in it yet, If we would've cooled it down for a couple hours, I know it would've went 660 easy.

Were jet changes made? With more timing it probably wanted jetting.
I would definitely jet up with it in the car to start with imo. |

The Tq looked a bit lower than what I would expect and I don't know the rest of the specs??... degreed & jetted?... I see degreed to 106
I did a 462 street engine with a much smaller cam & for the most part 90 less hp but about the same peak Tq Overall I'd say success Mr. Darby! You should have a fun season.

Thanks!!
What did u want to know Jeff? The Specs are on first page. Cam was a custom mike Jones can for this combo, degreed in at 106.4. Jetting was 92 square. We didn't even touch the carb, not even a mix screw!

Yeah I missed the ICL on your 1st post...
Pistons, etc whole build...if you don't mind? Is that the same custom Dominator I built you back in 2011? So you had 1 dyno day?? good that you got it on there in the 1st place.

Heads flowed that on a tight bench, on my friends 600 they flowed 347@800, YOU can do a search of before and after pics, the heads came from someone else n were ****ed up so I sent them out to be fixed.

Yea, there 368cfm high ports on 14:1 461 with 277/288@50 .485/.471 lobe lift and 112 lobe sep with harland sharp 1.65 rockers, im still impressed by your set up ive shared it with alot of my buddy's that's on PY, cuz was trying to talk couple of them in to buying a set of Kauffman D-ports, I never intended on going as far as I have but when I have people running that mouth I just kept buying stuff lol like full Calvert suspension and msd power grid system think I went a little over board but its there for the future now LOL
