The carb works well with the porting; after some jet changes it dyno'd at 615HP at 5800 rpm, 640 lb/ft at 4200 rpm with 90% of the peak from 2800-5600 rpm. It looks great sitting on my garage floor; I'll be sorting out plumbing & accessories and hope to install in about 2 weeks.

Thanks to a number of you for suggestions and advice, and particularly to Tom Kirkham for carburetor advice.

I'm taking mine back to Tom for a rebuild now. I've got 605 HP/613 TQ on a 482ci engine.

Good luck Mark. We hope to see you soon at Cobra breakfast.

P.S. My 850 carb wasn't ported.
