If you want to know about cams, there is a good article linked off the 62-65 tech page called "General overview article about engine cams and cam selection" - about 2/3 of the way down. http://1962to1965mopar.ornocar.com/techstuff.html Yes there is a whole system that needs matching. Discussing the complete car's weight / powertrain components with a Mopar-knowledgeable cam grinder is a good suggestion. Several vendors were already mentioned. Another favorite from past discussions here is Jim at Racer Brown Cams, listed on the 62-65 Vendor's page. Or you could sell the RB and put in a poly stroker. :) Heh heh Thanks, Gary H. > -------Original Message------- > > Yah, the piston people asked me that question and I wasn't sure what to > say.
