598 or 632?
i have been told 598 for heavy nos combo,
and 632 for light nos?
i am going to be hitting motor with 500 hp of nos or less.
just wondering what you guys think.
this will be a dart 360 headed motor with single 4.
pros and cons of both?
I wouldn't go 632".A 615" is a better combo for Nos in a 10.2 block.I don't think you can go wrong with either,but I think with that head I would stay a little smaller and go with a 598".I have both and they work well.
