Hey guys- I attached a video of the car running and some revs. Really curious if there’s something going on with the car. It sure sounds like a lot of whooshing/drone vs a nice exhaust sound when revving or taking off…sounds OK on idle. Here’s the current setup (purchased 6 years ago, always has been like this) Larry- curious on your thoughts as well! I see a lot of setups mostly stock with a 71 455 that sound so much better. not a cold start- hence the slight oil burn off Video: https://youtube.com/shorts/CJ3gHYQNpkA?feature=share 71 455 TR block, regular heads (stock) Stock manifold Stock intake 4bbl carb quadrajet 2.5”dynomax system with “welded series” mufflers Comp cam-Larry said in past post its your run of the mil Chevy cam. I forget specs but can look if needed.
