Yea, I know that I have several sets of each (ya know "borninamopar) but I don't think the 915 with the 1.72 exhaust would be legal to run on a 64 dodge with the 383. I think john was talking about the 66 915's with the 1.60 valves as that is what came stock in 64 in the 383. I may just build the R/T it looks like it may be more competitive anyway. I might build them both and see which does better.
