The Truck is a standard 79 "Explorer" F100, long bed. This is the original engine, I rebuilt it 6 months ago due to 165,000 miles.
It had to be bored .060 over to clean the cyl. walls. As far as running before the rebuild.... well, smoked like crazy on start up, power was awful. The power band on the Cam is 2000 to 4800.
I had a valve job done on the standard heads. No shaving. Original Distributor, new cap,rotor button, new wires, plugs. Timming mark @ TDC was dead on when I assembled the engine. Like I said earlier, I did not index the cam, I set it just like normal cam. Bottom end, new pistons, rings, bearings, ARP rod bolts, new HO pump.
What else????
I think I got it all.
I like the idea of switching out the vacume advance for weights, don't know if it means much but the vacume hose from the distributor is connected to the carb on the passenger side of the Edelbrock/Weber. Oh, one more thing, all holes in the heads for the polution stuff plugged with freeze plugs.
Wehn I rebuilt the motor I was expecting a bit more HP than I have, I don't expect much but just a dab more than I wound up with. I love the truck, it's a grocery getter, neighbors use it etc.

Thanks for taking the time to help guys!
