2Y vs. 2YABC
I am new to this site and I need to get an answer to a tech question about 460 cranks as I am in the process of building a 429CJ and planning to use 460 crank. What is the difference between the 2Y cranks? I know the years and such. But what if anything is the diff between the, 2Y, 2YA, 2YAB, 2YABC. Is the 2YABC better to use for high performance than a 2Y? I heard something about first level, second level, what ever that means? I heard that the 2YABC has more nickel or something? I have both cranks 2Y and 2YABC and just what to use the better of the two? I would appreciate any info you guys might have.
