I am going to be changing the cam in my 383 this winter. The last time I had the intake off I checked the lifters and it looks like a couple may not be rotating well. They are starting to get a wear pattern on them. My current cam is about .477 to .48 lift by dial indicator. I have no idea what brand the cam is or the exact spec, it was in the engine when I bought it. The 383 is near stock, it has been balanced and has had minor head work done. I have an Eddie dual plane manifold with a Holley 750. I will be running 3.55 gears with a 4-speed. Any thoughts on how much cam I can use and still have a fun driveable car with reasonable fuel economy? Also any recommendations on cam grinder would be appreciated. I have heard good things about Racer Brown. I talked to Comp Cam and they suggested I stay with something near what I have such as their #21-223-4: http://www.compcams.com/Cam_Specs/CamDetails.aspx?csid=707&sb=2 Thanks Dennis C. 1996 Dodge Ram 3500 Van Conversion 1964 Plymouth Belvedere 318 Auto 1963 Plymouth Sport Fury 383 4-speed 1949 Dodge Pickup 289/C4 soon to be changed 1998 Honda Valkyrie Standard ---- Please address private mail -- mail of interest to only one person -- directly to that person.
