hi guys , I require assitance, I need cannot remenber the small block chevy value lash for the first off road Z28 off road cam , the cam that was designed for the 1969 crossram 2 4 intake , please advise, many thanks, rojo

 

I this is GM 140 part number correct 1st design off road camshaft? Hot lash should .026 on the intake and .026 on the exhaust. These cams were pretty big for anything on the street including big inch small blocks. Are you racing your car in a sanction event?
