if everyone liked the same thing, we'd all be doing my wife!
Now that I'm long past my teen years (in the mid to late 70s) outlook of "MOPAR RULES! everything else SUCKS" those are a couple of my absolute favorite GM cars. The SD 455 was basically only lacking a better CR, IIRC it was in that typical 8:1 range of the era. I'm guessing doing whatever is possible to raise that into the 9 or 10:1 range would make a significant improvement? Maybe a cam change too? Beyond that, it seems like the rest of a SD 455 could handle the increased power. Could be as "simple" as a bolt on centrifugal blower.he had a few GMs too like a SD 455 Trans Am, and he's had a W30 442 or 2 over the years.
Sure... but is he happy?No doubt he is a man of impeccable wealth and taste.![]()
