Why not a 413 ?

Man, I found like 5 different articles that said 4.18. I guess the 75 was to much trouble to add on. Sorry about that

No biggie. It's kinda like the short stroke big block crankshaft. Everybody calls it 3.38 and it's not. It's 3.375. It's really not important for argument's sake, but it is when you get down to doing the machine work.
