Pushrod? I have the new F14 High lift cam 232"/234" .646"/.612" 112LSA with Morel/Lunati lifters. I know the new lifters are longer then the stock ones, does anyone know what size pushrods I need?

actually you will need some 7.450" in you have stock heads and gaskets and havne been milled. this is because your stock cam has .500 lift and now you exhaust is .612. if you devide both by 1.7 you will get
.646/1.7=.380
.612/1.7=.360
.500/1.7=.294
those are the actual lobe lift now if you take
.360-.294=.066
.380-.294=.086
you need a .066 longer one for you exhaust and a .086 longer for you intake. 7.450" is the closest you will get with out having too much preload.
but you have the morels so you need to find out how much longer they are then the stock ones and how much preload they like. but if you had stock ones this will give you an idea.
