340 vs 360 confirmation

I took the headers off my 69 Cuda with a 360. They drug over every bump. I enjoyed removing them….. I used the 72-73 340 exhaust manifolds, they fit great and work great for a streeter. I doubt that you would notice any difference other than your wallet.

Yep! The previous owner installed the absolute cheapest headers on the market. The flange literally drags the dirt road I live on, and going in reverse is absolutely out. I went to raise the front torsion adjusters, but the center link is already hitting the lower header tube, and of course the link passes through the headers. So yeah, stock manifolds all the way.
