i have a 56 f600. it has a 292 in it.my problem is, is that it has a bent push rod.well one guy gave me one out of a 272 who said it was the same,wrong. then i gave one to another guy who brought it to a man that knows these engines well,and he didn,t have one.well i'm starting to think that there is a difference between a truck 292 and a car 292. meaning every pushrod that everyone comes up with is to small in diameter and a tiny bit to short.so how would i go about finding the proper pushrod. thanx
