Want to follow up on this one.  Jim worked with me on another camshaft iteration for this engine.   

I did another hydraulic roller camshaft for it and we ended up with 687 hp @ 6100 rpm and 639 lb-ft of torque. 

These were unported TFS heads, with a Tunnel Wedge.  10.9:1, pump gas.

Very nice!

Picked up 40hp at same rpm with a cam change, was it losing valve control?

This is yet another TFS combo making great power without having to spin it too high, they really are impressive

Goals changed from first customer to second….
