This is my work in progress thread to my 1977 F150. I purchased the truck as a stock 2wd swaped 351w / C6 truck with a 2.72 9" rear end. The minute I bought the truck I knew I was going to swap it to EFI but it needs to be done affordable as this is going to be my run around the shop work truck. I also know overdrive is about necessary these days so that needs to be in my upgrades to gain more power and fuel economy. This truck will be a daily driver so no antique tags for it. It will need a Virginia state inspection when complete(no smog here). Here is the plan: Engine: 351w roller block, Explorer GT40 heads (.5" head bolt holes) Intake: Knock off PP 351w mustang intake Fuel system: Mid 90s F150 factory rear tank setup. Ignition: Stock Explorer coil tower ignition with modified cam pos sensor and damper dudes 28oz explorer balancer for crank trigger Belt drive/timing cover: Factory explorer 5.0 Exhaust: Long tube summit racing headers w/o2s welded in. Truck will stay true dual with single MagnaFlow cats, probably no mufflers. (Cats required for state inspection) Transmission: 96 Explorer 4r70w 2wd Flexplate: Mid 80s Crown Vic LTD w/351w and AOD Computer and Harness: 97 Explorer XDT3 pcm w/ full harness Rear axle: 9" w/3.50 gears (eventually 4.10 or 4.11) I posted this in the need for speed section as this applies to anyone wanting to upgrade their explorer to a 351w using stock pcm (although I don't have oil pan or header concerns). Here's a pic of when I picked it up. I've had it for a little over a year now and had it running before it came in the shop.
