Setting valve lash on a 383 with a hydraulic cam
What is the best way to set valve lash on a 383 sbc with a hydraulic cam and lifters? I have read of couple different ways and one sounds very messy. This is my first engine build up and I am trying to do everything myself so I can learn how to do it. I did a preset a while back and can't remember which way I used. I took the car to get an exhaust system and one of the mechanics there that builds engines for race cars said it sounds like I have 2-4 valves that are to tight. Any advice would be helpful.
Thanks in advance
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
