Mopar 284/528 mechanical camshaft

Rebuilt kb piston 340 9.5, ld340, hedman headers, 4 spd, stock x heads, 4.10
.528 cam installed at 107 or +5* adv 16mpg fwiw.
33 total by 2200rpm is all it liked.
3320lbs
Tire spinning 13.80 et.
The .528 cam work its absolute best 8-10 degrees advanced. It breathes fire and fires tires with the slightest goosing.
Slicks are a must when installed like that.
Mileage WILL be 9-10 mpg.
You literally lose about 6mpg as a bi product of 8+ advance.
The above combo with .528 I bested 16mpg @107

Just some of my experiences with that cam.
440's love it
