302 stroker
I have a 1989 bronco 4x4 custom w / posi trac frt. & rear I use this for my mower shop tow truck. 302 was very slugish it blew up. I was going to install 351 but I ran across a stoker site . I pulled engine ordered347 stroker kit , ordered mass air kit , K&N air filter,24 lb injectors cheper than rebuilt ones, complete roller cam lifters ,rockers & roller chain. Stroker kit came with New Probe pistons , rods, steel crank,chrome rings, federal mogle bearings . Bought most of the parts at summit ,oil pump & heavy duty pump rod , the old one looked like a twisted pretzel . Camshaft custom built by comp. cams thay needed to know what I was using the Bronco for wt., tire sizes , gears in rear axle ect. . I also rebuilt trans AOD . Used Bronco it to pull my sons truck engine blown up away from home 85 miles away , I could not tell it was there . Bronco was built for tourqe it has it !!!

congrates, need to go get some dyno pulls done. my only concern would be how long that motor will last. havent heard to many get to 100k miles. the 351 would have for sure but having a stroker is way kewler for sure. what did the final cost come to.

Probe pistons have been proven to go 150,000 & up . I forgot to say I used 9.2 to 1 pistons to keep the bottom end together use no higher if you want it to go the long haul use 10w30 oil change every 2500-3000 miles to get extra mileage from your engine.

dss puts out a pretty good product. a mustang friend of mine had one of there 306 shortblocks . was a nice motor.
if i was to stroke a 302 the 331 would be my choice. i opted to swap a 351 in to replace my tired 302 because its just a better motor and more reliable. I can put heads , cam and truck intake on the 351 and have the reliability and more hp/trq then the 347 for less money. . yomow i hope your not taken offense by any of this. i will eventually probably stroke my 351 to a 393 but not for awhile. gonna start a kid farm hehe.

It's all in the camshaft & cyl head's when doing strokers . I did not do head's just rebuilt em . All I wanted was tourqe HP. If I put on alm. cyl head's & Better intake I would have got Extra 100-125 HP. again all tourqe is what I wanted. And I have it . AOD trans. is not to good w/ to much extra HP.

It's mostly the torque that tears an auto tranny up.
An aluminum intake mabe like edlbroch can give you more torque and hp.

I believe the longevity issues with the 347 stroker is oil supply to the upper engine. Sounds like he has taken care of that be not going overboard with the heads.
As far as which engine is better, it comes down to opinion. I like both engines . . . they both have the positives. In reality, they are both Windsor type engines so there isn't that much difference in mechanical design.
The whole advantage the Windsor had over the Cleveland family was a lighter block which is also a disadvantage when one wants to over bore. The Cleveland got caught in the never never land on the smog rule development and ford adopted to abandon it in favor of the Windsor group.
Ford screwed up badly by ditching the Windsor group and the 300 I6.
Just my .02 on the 302. Keep us posted about how it goes. I will probably do a 331 or 347 when I build a new engine for my Bronco.
I currently have a 302 in my Bronco and 351W in the F250 SD
