He says he likes it a lot. His is a 408 so the step up to a 426 shouldn't change much especially seeing as his is under driven. If I remember correctly he is running 7 lbs of boost. I don't know what version he has. I can't answer your question on if it breaks a belt. I know my 8-71 will run without a belt. Not that good but it will run.
