Hi, I have a 95 ford 1 ton dually single cab with a 351w. small block in it. I want to build a bigger engine to go in it. I want to use it as a daily driver, so i want to still be able to run 87 octane. But i want to be in the 300+ horsepower range. does anyone have any ideas To get me started. My knowledge is limited on engines. Any advice would be great.
You have two simple options for legal reasons, you can go with a stroked 351 or a 460. A junk yard 460, honed, and refreshed will most likely be cheaper than stroking yours or buying a stroker motor.
For 87 octane, you can't run much over 9:1 compression or a lot of timing. But ported and polished heads with a good tune and cam should get you over your goal.
How much horsepower will a 460 give me, I want to use the truck to pull trailers with.
go for the 460 with trialers. I like my stroker 351 windsor but it doesnt have the lowend torque of a big block. Screams like hell up to 5500rpm though

It all depends on how radical you want to go. Ford had a set of 429/460 aluminum hemi heads, an aluminum block, a 500+ci cranks, worlds of different cams, electric cooling fans and water pumps, intake manifolds, ect.
The 460 is better at pulling trailers since it can produce big torque at lower RPMs, thus wearing less, but since you already have the 351 and the tranny that goes with it ( you'd have to swap trannies too w/460) financially, I'd stay 351. They can produce pretty good power while maintaining dependability.1st off is this an automatic or stick? Anyway, look into a GT40 lower intake ( must be for the 351 the 302's is narrower), an explorer/cobra GT40 upper, either cast iron GT40 heads ( not the "Ps") or Y303s, X303s or the like, a mass air controlled ECU, mass air sensor, map sensor, 65 mm Tbody, good set of stainless or really well coated long tube headers ( headmans/hookers) true dual exhausts with H pipe or cross over. The cam selection will depend on your tranny & rearend gears. & if you're running any gears higher than 4.10s swap'em out, 4.10s-4.56s will PULL and allow the 351 to hit a higher power curve. PS- since so many of the 5.8's parts interchange with the 5.0l there's a huge aftermarket that stays competatively priced and vastly versitile, the 460 stuff is more expensive with fewer options, or at least fewer suppliers. BUT if $'s no object, bigger is always better.
HP doesn't tow trailers, TQ does. 300HP is dumb easy with a 351... just let it breath, but it still won't tow like a big block. How big a trailer are you pulling? You'll need to replace the engine and tranny to run a big block, and it'll suck fuel like you won't believe... single digits around town and hauling, so you gotta be prepared for that.
A 5.8 with upgraded intake, heads, cam, and exhaust, computer and fuel system will be pretty respectable, about equavilent to a stock big block, but cheap is not part of the formula. The '95 5.8 is a roller motor.
My thinking with the stroked 351 is that he's be better off selling the truck and buying one with the EFI roller 460 rather than trying to swap engines. He can buy a crate stroker, or, since his block is likely to either be a roller or at least accept a roller conversion, stroke it and make it a roller, he can get most of the torque of a 460 without having to sell the truck. And it should be able to use the stock EFI system.
The common stroker setup uses the stock 351 rods and off-the-shelf 5.0 pistons. That one gets 393 cubic inches. With the roller cam, that should have a lot of torque. There' also a 408, but that usually requires new rods and custom pistons.
godblessmudd- what do you mean the trannys are the same??? 351w,351c,302 and 289 all share same bellhousing. 351m,400m.429 and 460 share same bellhousing.
as far as the rest, if you have a 1 ton im assuming you haul a big enough load to need it therfor i would recomend the swap to a 460. even with a stroked 351 its not going to last as long as a mild 460 at the same power level. 300hp for a 460 is a switch of the cam and headers. add the cost of a rebuild kit and your lookin at maybe 1000. a tranny depends if you want new, rebuilt or junk yard. but all and all still under the money its gonna cost for a 351 stroked. as far as gas milage, once you put a built 351 in a 1 ton and then tow with it its not gonna give you enough better then a mild 460. and what little it does will not offset the cost of the build and rebuild there after to keep it reliable. reason being. 460 make power down low with right cam usually less than 4k. a stroked 351 is going to have to be at that or better to move the weight that you would need a 1 ton for.
