On the search for push rods... i've been looking at manleys stuff but looks like their are 2 diffrent sizes 3/8 and 7/16. I read on mortecs site that 7/16's was only for racing, high lift, or high open spring pressures.. I've always heard the push rod is suppose to be the weak link for when theirs a problem so that the push rod hopfully bends before other things break. I dont want to beef them up too much and possible cause worse damage if there ever is a problem.... So the question is what are you guys running 3/8 or 7/16? Not sure what i pulled out of this motor, i'd have to go measure them lift is .640 and open # is 540
Also, push rod lengths... do i need a measuring tool or can i just go with a standard length? again it's a 467, 990 heads, hyd roller cam, solid roller morel lifters, scorpion rockers...
