I’ve set the preload but there really noisy, horrible clacking sound, is this normal for these lifters? I have read that others have had the same problem

Hughes say 1 turn from zero ‍♂️

Hi, I’m in the process of building a 408 stroker (360) with the aim of 500hp. The cam I have is from Hughes SEH4652AL-6 which they put together with stroker kit. This is mainly a street car which is a B body and I was after some advice on the intake choice and is there anybody running this cam...
