Hi I have a 88 f150 4x4 it came from the factory with a 6cyl and the guy I bought it from swapped a gutless 302 into it. I'm not sure what's been done to it other then a edelbrock performer 289 intake and a 1406 carb. Ive had it for going on 3 years now and every now and then it would run rich but lately it has been real bad. I only get about 8 mpg if I'm lucky. It has a c6 trabs and As far as rearend gears it has 3.55s. I was looking into swapping a 302 with the gt40 heads from a 96 explorer and running a carb on it and upgrading the cam. Was just wondering what everyones thoughts were and what is a good cam for a everyday driver/work horse. I haul trailers and recently added a plow to the truck for a back up plow truck. Any help would be appreciated
Not sure why you'd want to replace one 302 with another. Were it me, I'd find a roller 351W and swap that into it and gain some badly needed torque. 302's have never been good truck engines. Just the roller 351 with the stock cam would do wonders for torque.
What years were the 351w rollers? The only reason I was going to swap the 302 with the gt40 heads is cause I can get one from a local junk yard for $300 and my intake should bolt right up. With a cam swap and intake/exhaust it should make over 300hp. Plus I just bought a gm hei style distributor for my 302 that's currently in the truck and I was hoping to reuse that after I just spent $100 on that alone. Here a link that got me thinking about the 302 roller http://www.carcraft.com/techarticles/1408_make_503hp_with_a_350_junkyard_302/

Ford motors are new to me. I grew up wrenching on small block Chevy's. I know heads and intakes are all interchangeable for small block Chevy's. Just not sure about ford motors
Yea, you can put a GT40 headed Explorer motor in there, and get it to make 300 HP, but it's still going to be missing what you need in a truck, and that's torque. You can either spin the snot out of it to get the torque, or do it at a lower rpm with a 351W based engine. In addition to that it's going to be hard to get to 300HP with the Performer 289 and the Eddy carb. The roller 351W's started sometime in the 94 model year. The last ones were in the 97 model year in the F250/350. Plowing snow and pulling trailers, you need a 351W at a minimum, a 302 will never cut it. Really, the 351W leaves a lot to be desired pulling trailers too, especially if you've pulled things with something with even more torque, like a 7.3 diesel
If this were a Chevy truck would you put a 305 in it or would you go straight to a 350?
That said, if the existing motor is from the smog era(1975-1986) it's a low compression 150hp lame duck and swapping in the Explorer motor will be a hugh upgrade, without doing a thing to it but strip off the EFI stuff and mount the carb and intake you have a 250hp motor, add longtube headers and it'll make 350tq but that'll be little ways up the tach, below 2000rpm there isn't much grunt since this is still just a 5.0. But I say start with that and see what you think, if it's still not what you want then track down a 351, swap the GT40 heads on and swap that in.
