Call this Man.
661-257-0101 Tell him you got his number from the DeShongs. Ask for Jim. I dont know if you have heard of Jim Grubbs Motorsports in so. cal. but he knows his stuff. He pumps motors out all of the time and has built motors for members in my club as well as family friends. I plan on getting my motor to him end of summer to have it built to a 331. You tell him what you want and he can give you a heads up with what you may want or not want to go with.

You got any idea on what parts he's used and what kind of packages/prices some of your buddies had done?
Thanks,

I wouldn't spend the money on a mail order shortblock unless you are going with a REALLY big name like Keith Craft, Bennett Racing, etc. I'd just buy a kit and have a local reputable machine shop do all the work for you. It's much easier working with a local company in case of problems then someone out of state.
Get a 5.315" rod 347 kit. Rod ratio arguements will never be proven to any degree of certainty between these two motors. No one can come here and throw out a blanket statement that a 331 will last "x" amount of miles longer than a 347. They will both last as long as the driver allows them to. You will long pass the limits of the stock block with upgrades on either motor before you wear them out.

this is the president of the Mustang club Im in. This is a great setup. You can call him and ask him any questions you have. He may not be local for you but he will give honest answers and let you know what combos are good. He can let you know what works for what. Jim Grubbs has a big reputation here in So. Cal. and has built just about everything. I hope that helps.

I voted for the 347 kit.
Reason is that I've always had a GOOD machine shop do the machine work and balancing. Then I put it togather myself.
The block grinding I'd do myself.
The story about the rings on the 347 was resolved several years ago by the quaility type engine kit folk's.
A quality engine kit is the only one I'd consider like from DSS or Coast. Kieth Craft has nice things too....
