Wow, great timing - I just picked up an '85 351W (carbed) to rebuild for my eBronc project.<br><br>How you plan to use it determines how you build it. Mine's going to be mostly a trail truck, but I do plan on driving it around town a little. I don't plan on racing it, mud running, sand dunes, or tractor pulls, just playing around on the trails and rocks, and I don't want to have to worry about it. I don't want to have to run octane booster to prevent detonation or a $400 aluminum radiator and all kinds of coolers and fans to keep it from overheating, so I'm going pretty simple on the engine package. Just a rebuild, really, concentrating on reliability and throttle response. <br><br>Rings, bearings, gaskets, double-roller timing set, oil pump, oil pump drive shaft, valve seals, and an "RV-grind" type cam (260 duration, .450" lift) for great off-idle torque, headers, and a Q-jet (again, for throttle response..and it's great on hills). <br><br>I picked up the core engine complete for $150 at a salvage yard, and the PAW rebuild kit is less than $200. The Q-jet, headers, and Bronco 351W swap oil pan I snagged on eBay for about $120 total.<br><br>The great thing about a 351W is that it makes plenty of torque (350+ ft-lbs) and horsepower stock (300+) - you don't have to go crazy with parts to get power. Of course, if you plan on driving your EB in ways that require more oomph, you can always build it stronger..and cheaply.<br><br>You can go EFI, stroker kits, single-plane intakes, aluminum heads..anything the 5.0 Mustang guys do to the 302's can be applied to the 351W..(and that' a LOT.)
