OK guys just humor me, I know this has been asked a lot. Looking for recommendations on what cam to put in my 1970 Chally R/T, the engine is being rebuild right now by a shop in Rockville, MD.
The car is a 4-speed and I will probably keep my 3.23 gears. It's a 1970 engine, Holley 650 vacuum secondaries (yea its a bit small), Edelbrock 2191 intake, stock heads, 1 7/8 inch headers. I drive street only - someday I might take a pass down the track but I'm not a drag racer.
I want to avoid wiped lopes. So someone mentioned I could try a roller cam, but after reading around a bit, I got mixed feelings about going that route. Do I just get a bronze cam gear or do I need bore bushings, etc? Does anyone even make a mild roller cam for a 440? Almost sounds like it's not worth it.
So the other route is to stick with flat tappet hydraulic. My builder said he could play it safe and get a Purple shaft, such as a MOPP4529270AE.
I've heard good things about those, and also bad. And the same goes for Hughes, Comp Cams, etc. For example Hughes practically guarantees against wiped lobes and then I hear someone else say they wouldn't ever buy one.
Bottom line, looking for your recommendation on which brand to use and the specs on it, for the best and most reliable grind to make good power 0 - 5500 rpm. And no wiped lobes
thanks,
John
