Here's a great thread with lots of info, specs, and videos. The video by voetom is a good one. Stock 4 speed cam at idle. He makes his own mufflers and the second vid is with them open. https://www.forabodiesonly.com/mopar/threads/340-cam-specs.53607/Yes, I agree 100%. I don't grind cams, I just buy them based on specs to hopefully function well and perform. This one does just that, especially since a '67 Belvedere wouldn't have had a 340 anyway...
Great sound for sure.
