Re: Looking into ZZ383 crate motor different cam option?
These zz motors are mostly stock with hydra roller cams. Might check with the selling dealer for cam selection as I don't think you have many options from gm.
Last zz383 short block I did for a friend we did change cams but it did not have the thumper sound you are looking for.
The cam we used was supplied by lunati for us as there were no new cores available then.
This is a steel billet cam. I may have the part number somewhere. But not a potatoe-potatoe sounding cam.
Forgot to mention we ordered the 425hp version of zz383.
