Let’s hear a 340 story

I still run a big duration camshaft and six pack setup with 391 rear end 4 speed and a good set of aluminum heads. The old girl still makes people's eyes go huge when I hammer it, yes times change but it's still a pretty respectable and fun package.

Way off topic but Mopars are a screwy animal. They seem to love big carbs and lots of duration. I still have two of my old big block cams that I used to run 9.80’s with stock 440 junk parts back in the late 1980’s. 286 (332 duration). I’m way behind the curve running a 750 and now an 850 carb on my small blocks but I will be stepping up to a custom built 1000 cfm this year. But if you think you can just take a big carb out of the box and go fast with it you are better off sticking with a smaller carb.
