Edelbrock RPM XT? - 01/27/09 01:29 AM
Does anyone have information on the Edelbrock RPM XT big block head? There is a tab on Edelbrocks web page, but it just says coming soon?

They are a CNC ported version of the RPM heads.Looks like there will be combustion chamber work done as well.

They are a step up from the stock rpm heads.
225cc intake port size.
100cc exhaust port size.

Stock location intake and exhaust ports.
They accept stock rockers.
They are taking orders but have no release date.
