Ditto X2. As some of you know I am currently building a 421 Cub. Sure it is not as big as the 10's and 16's but I wanted a crank that I could depend on. I researched several cranks and spoke to lots of people before my purchase of an M&M crank. What made me the final sale was the customer service and the ability to call Andy with any problems that I have, before, during and after the build.
Sure you can buy a crank on Ebay for $400, but do you really know what you are buying and who you are buying it from? After you put it in and make two passes and your motor gets jacked up other than a name on Ebay who do you personally call? Do the research call the builder or supplier and find out what type of customer service your going to get after the sale!!!!!!!!
