I was just wondering what size push Rods I will need for my build. I have a set of gt40p heads with Alex springs, comp cam magnum roller rockers, comp cam lifters, and a 270h cam. Any kind of help would be awesome thx guys/gals!!
Are the heads shaved/milled?
Best thing is to get/borrow a pushrod length checker. However, on average they can be anywhere in the 6.250 to 6.300 range. So getting the tool to measure would be your best bet.
