308 head & XR280HR-10 Combo

I knew I had forgotten something..750 CFM Holley. They just cut for new seats, guides are new too.
444 Max torque on DD looks pretty good, but it happens early then falls off quick.
363 Max HP?? I thought this would certainly crack 400 HP?

The Comp Cam Utility (CamQuest)is even more harsh...HOLY SMOKES!!
406 Max Torque
306 Max HP.

I assembled this engine about 2 year ago, and it's been bagged on a stand since then.
I remember convincing myself to not overbuild this project, but I certainly want it to be worth the time and money..

Sorry, but if they just cut for the new seats I wouldn't expect any more flow than with the 1.88 valves. You gotta know what you are doing when you install bigger valves or you can lose flow!
