Hey everybody. I finally got a car. It is a 1968 Rally Sport with an original 4 speed and maybe original 12 bolt posi. It has a ZZ4 350 crate engine that runs great. The only thing is that you can hear the roller rockers a little. The engine has about 400 miles on it and the guy I bought it from said they will need to be adjusted a bit at about 1000 miles. I talked to my friend who has a very nice 350 engine with rollers and he says his are as quiet as can be.
My question is whether this is normal for a new engine or is it an easy fix?
Thanks for your help

Congrats on the new car. Sounds good. I don't have very much experience with rollers but it sounds like they need to be adjusted. Then go from there.

a ZZ4 isn't built with roller rockers from the factory. it does, however, have a roller cam. i guess maybe roller rockers could have been added. the rockers are adjusted the same whether they are rollers or stock stamped steel.

I have noticed some roller rockers that seem to rattle somewhat and others that don't, even if they are both adjusted correctly. It must depend on the manufacturer and how they are made.
Congratulations on the new car! I hope you enjoy it for a long time.
