351 4-bolt main??
I am interested in buying a 351 for racing purposes. I was wandering did ford ever make a 351,351M with 4-bolt mains. and if so when. also, I will probably be turning this engine in the neighborhood of 6000 RPM. Would I definitly need a 4-bolt main to stand up to this.

A properly built Ford motor, balanced, blueprinted, etc. will handle 6000 RPM on 2 bolt mains very well. Remember, we're not talkin about those "other" motors that need 4 bolt mains and steel cranks to turn the Rs
Ford racers have been doing it for over 40 years.Nathan

If you want a 4-bolt main Windsor, you can buy them from SVO Ford

Part #: M-6010-S351 cost about $1700 US.
A cheaper alternative would be to use a stock block with a "main cap girdle" which ties all the main caps together to prevent "cap walk". This setup will easily handle 7000 RPM.
