I ran a Erson 270 grind in a slant 6 for years. I would love to have another, along with a 280! With a 270 cam, 3.55 gear, 833od, mildly ported head with big stainless valves, a super six intake, 2.5" exhaust, and a mopar electronic distributor using a gm hei module, my 84 swb truck would pull a proven 25-27 mpg at 70 mph, if not bucking a wind over 15 mph.
I ran this cam for over 75000 miles with no issues whatsoever. A lot of people thought it had a healthy small block in it. It sounded really sweet! I was never kind to that engine.

84 D150 440/727
79 /6 swb D150
1964 A100 window van. Just because it has spark plug tubes doesn't mean it's a Hemi.



If ya haven't been there, ya just wouldn't understand.
