My version of a factory parts build 318

In my '69 Dart, I dialed in 9.00 and ran 9.02-3 (1/8th) every pass on my way to redlighting in the finals with a stock piston 318, stock 915s with 1.88/1.60s, RPM intake, Headers, MP474 Purpleshaft, and factory converter w/ 3.91s. I can't prove it now but I pretty sure a set of stock 302 castings would have slowed me down. I'm a believer in the 302s but only when worked. Stock for Stock.... give me the X, J, O, U's for a 318! My times aren't earth shattering but for factory piston 318's.....
