That sounds right, 1.8's on the intakes would make it close to 0.700"

Jim doesn't belong to this board however he certainly deserves a little credit.
On the first video it looks like Tom Earhart's dyno---don't let the simplicity of Tom's dyno fool you----Tom is one incredibly intelligent guy.

"JimV" is a member here and for many years---he just doesn't post as much as he used to. If there is anyone who can get the most out of a set of heads it is JimV.

Hey guy's thanks for the nice comments. The engine was dynoed at Tom Earharts (thanks again for the help). Cam specs 236/244 .646/.651. Here's the results

rpm..........CT...............CHP

2000........616...............235
2500........630...............300
3000........659...............376
3500........657...............438
4000........725...............552
4500........757...............649
5000........765...............728
5500........746...............781
5750........716...............784
6000........671...............767

I will be pulling my heads off to remodify the intakes. This motor made an average of 39.9 ft lbs more torque thru out the curve with peak of 74 ft lbs @4000 rpm.

Thats some really decent power. I have been wondering how those Brodix heads performed. I do not know anyone that runs them, but have heard stories + and - about them.

Thanks for sharing
