I was just wondering if anyone had a dyno program and if they could run my motor on it. All my specs for my 383 are below. I will be running a dual plane intake if that helps, probably a stealth or a holley. Thanks, Danny

 

To get an accurate run we need more specs than that. We need the airflow on those heads, duration and intake centerline on that cam. And i'd check the comp ratio math again. If your running a domed piston on a 383 you'd need a pretty good sized combustion chamber volume to get it down to 10:1. if you run a 64 cc chamber your more likely to be around 11.5:1.

 

Tell me about it!!!!!!!!

 

Im running a 76 cc head. The guy at summit says that ill be running at 10.1.
