Its a stock 1974 454 with 1978 781 heads in a 1979 truck, probably about 8:1 comp, 4:10 gears, 4800# truck. Only thing not stock is the headers and exhaust (dual 2.5" magnaflows)
36 degrees total timing sound good? All in by what? 3000 rpm? Maybe I should just buy the advance kit, get the thing tuned and be done with it. This truck sure could use more MPG. As i'm sure you can imagine. Any little bit helps.
