Today, dollar for dollar, is the 318 faster than the 340 ???

Back in 1977 when I was stationed at Ft Ord Cali we had Dodge M880's with the 318. The maintenance Sgt was also a Mopar nut.

On a 4 day week end someone ripped into one and replaced the 318 cam with a 340 Auto cam. Someone else took the heads down to a shop and had 0.020" milled and then pocket ported them.

Fastest M880 on the base but it was hard to tell anything was different sound wise.
