Wow what a great car. Yes an air car too. Really makes it special. Don't let that one get away

This was a classic dead lifter sound. Very loud. I didn't have a stethoscope then so I used the wooden stick method to determine which hole. Pulled the wire & then cylinder died so I told the guy it was fine just drive it. Hoping it would clear up. I used the Stock rockers & pushrods. When he brought it back a few days later it was quite. I figured a piece of trash had worked it's way into the lifter. I think it was a .480 lift cam. He called Comp & this was what they recommended. A 73 Charger 318. Did intake & Holley 600. ***** would run.I have yet to hear anyone say their valvetrain wasn't more noisy after using a Comp cam.
Someone once explained to me about it having to due to ramp angles Comp like to use.
I dunno. I'll vouch that they are noisy tho...
