1969 Plymouth Satellite

Hi New to this board. Thanks for accepting me. I just got a rust free 1969 Plymouth Satellite that came out of Ga. the former owner was redoing a lot on the car. It has the 318 motor cam,{he had just replaced}high rise manifold 4 barrel carb, and I put on headers and dual exhausts with cherry bomb mufflers.{it has no exhaust system} Questions is I got it home and got her road worthy again. The motor was quite but now the lifters are chattering, she still runs like a scaled dog but I am not sure if the former owner replace the cam and use the old lifters? Any ideas what to do or look for.Thanks Bruce.View attachment 1715453366

Nice car, looks to be in amazing shape. Decades ago when our kids were small we had a '69 Satellite wagon the same color. It had the rear facing third row seat and the dual action tailgate. The kids loved to ride back there and so did we! It had a 2bbl 383 with a lot of spunk. Towed our pop-up camper on a lot of great adventures. Thanks for bringing back those great memories and welcome.......
