340 cam change

I ran a Mopar Performance 284/484 cam in my 340 and thought it was about right for all around performance. Great on the street with 18 MPG and turned 14.50's at Bandimere (5800 ft, and 8500 ft altitude corrected), so in the mid 13.50's at sea level. Timing is everything with the 340 (and with any engine for that matter). I like 12° initial and 11° distributor advance (22° at the crank) for 34° total. Starts instantly and runs great.
When I restored the Cuda, I put in a different 340 with a Crane 272/280 cam that I got years ago (1990's). This engine is great for the street with good power but excellent manners. I am running 2.94:1 gears so I can cruse at highway speeds in the mountains where 70 is the minimum speed you want to go.
