How many miles does it have on it? i have beat and beat
smallblock mopars and never had a bent pushrod in one but it is never out of the question I have a 170,000
mile 318 in my 83 Dodge ramcharger 4x4 and it run's like a top and im not easy on it either. but would check your pushrods first like Chryco said it would be easiest to do then if all looks good there would replace lifters
and they aren't that expensive. And a piece of cake to do!
