CCX33911,
The Crankster is 100% correct on this one!!! Ryan Newman is running a Penske/Jasper motor... Penske & Jasper Engines teamed up to build NASCAR motors about a year ago...
All Winston Cup motors have a max 358 C.I. with 12:1 heads & holley 830 CFM carbs... The "BLUE" camp all use SVO 351 Windsor blocks & most are using Yates heads... Beyond that, even a "Top Secret" security clearance ain't gonna give you much additional info...
In the Craftsman Truck Series, we use an EEI (Ernie Elliott Inc.) motor and our motor tuner, who works for Ernie, and goes to all the races, won't even discuss the internals!!! Not only that but he used to work for Yates & doeesn't even know the internals of Yates...
I know this ain't much to go on but it's the gospel... Try
www.jrsgarage.com for used & new racing parts... he has everything including new motors & race cars...
