You didn't say it had to be a Mopar:

Diesel in the 67 109 Land Rover:


427 (I think) in a friend's 70 Chevelle. Can you tell he is a marine painter by trade



The old 383 in the 70RR. Yes it is dusty. If you lived a mile up a dirt road and were driven every day you would be dusty too:



New 452 at DRAM's shop right after he made up a set of plug wires. Should be going on the boat soon.
