Ron,
670hp ?!?!?
I'd be interested to hear just how you've got up to that figure.
I'm not suggesting for one minute your car doesn't make that much. I don't know much about the various options for these engines you see, so am keen to hear what others have had done in order to get the figures.
For example, what's special about yates heads ?
Cheers,
John.
p.s. appologies for taking this thread slightly off topic. Might be worth mailing me instead...

John,
The engine is not a Cleveland as the quote onder the pic says.It is a 9.2"deck SVO Block,Bryant crank,Carillo rod Ross piston,.680"lift solid roller cammed dry-sump engine.
It was originally built by Robert Yates Racing for a Winston Cup team.My engine builder(MME in southern Md) lowered the compression,reworked the Yates C3 heads added lower ratio T&D shaft rockers and supplied the custom roller camshaft.It runs on pump gas,revs to 8500 RPM,never over heats and made 657 hp at the flywheel.The Yates heads have raised intake and exhaust ports and a unique combustion chamber design all designed to make tons of power.If any of you GT40 owners in the Maryland area want to trade a ride when the weather breaks,let me know .I would be happy to help.I have yet to even ride in a GT40.
Later,
Ron
