so it took me two weeks and some annoyance, But I read the whole length and am stuck on the single plane crank in a 350 I had originally thought short stroke big bore itbs would give me the sound I was after, but 180 degree crank would help imensely. I fail to see the reasoning behind 10,000 rpms I built my stock car to do 7,500 all day long. the other thing i am not sure about is power I think a 250 horse motor would be fine with me and then throw on a twin turbo should be good but will that adjust sound greatly? I dont think it would but turbos are not an item I am familier with.
