Please post the part numbers for the down pipes and donuts. I have the same situation with a '63 GMC with a 355SBC. The rams horn manifolds that I have are 2 1/2" outlets and straight down. They appear to be the same that I had on a '62 Impala with a 300 horse 327. By the way the bell housing crossmember has been removed from my GMC.
