stroker or built 302?
Hey i am working on a 55 efie and have a 302 hooked to a aod. I would like to get the full potential out of the little engine. My question is does the $2000 plus price tag of stroking a 302 to a 347 worth the extra horse power? Hot Rod magazine had a pretty good article on stroking a 302 and hp results were about 390. How much can you expect out a strongly built 302?

the 347 strokers have serious oil burning problems due to the piston design. and they will make the cylinders egg shaped faster then a 302 since the wrist pin angle. you can get a 302 to make a big amount of power. go to summitracing.com and do a search on crate engines. check out their assortment of engines.

So you would recommend just building a strong 302? I would like a really bad *** street truck. Considering i live 3 hours from the closest track and have no plans to move, building a over the top truck is out of the question. Also I am building it EFI.

i built a 302. .060 over hyperuetectic speed pro coated pistons with a mellings cam 286 duration. mellings high volume oil pump weiend 4bb intake 600 edelbrock 4bb carb. i have the heads rebuilt but i am going to put some gt 40 heads once i put this motor into the tbird. i have the motor in the truck now but i need a stall converter. but it is still quick and a fast reliable motor. or if you have a 351 you could build the 391 stroker. it won't burn the oil like the 347 i believe but it will still wear the cylinders quicker

I am presently building a 302 from a 84 Bronco to install in my 94 Ranger, .060 over, Edelbrock performer rpm heads(1.9 inch intake), performer plus cam and intake manifold, Holley 600 cfm electric choke carb, MSD Blaster ignition unit and coil using a stock distributer long tube headers w/ Flowmaster 70 series dual in/out muffler. If I've done my home work correctly I should net about 315 hp and 350 ft lbs at the crank. My buddy built a 347 stroker with the Edelbrock heads (2.02 inch intake)a serious cam and a Holley 750 cfm carb etc. and said he wouldn't do it again for a daily driver.

My initial thought was for $2000 you can get a 351 and build it very well, and that is for the $2000 you plan to pay for the stroker kit. Otherwise, sounds like racing isn't your concern, so build your 302 with a good set of heads, and a cam manufacturers recommended grind for your application and you should be happy. The article you read in Hot Rod may have used a cam that made hp high in the rpms and little torque down low, that is what your after, low end torque. Just a thought, good luck with your decision

I got a 302 bored out .030 with a 461/470 lift crane cam, long tube flowtech headers, 2 barrel motorcraft carb, stock intake, stock heads, and k&n filter. Would swapping in a performance intake manifold from maybe edelbrock of weiand be good for torque and can I get it to work with the stock carb?

with a non stock cam you are supposed to have an aftermarket intake and carb to have the full benifit of the cam's power. but yes you could get an after market intake and then buy an adapter to bolt on a 2bbl. although i would highly recomend a 4bbl carb.

Thanks for that input. Now, can you tell me which intake would be a good buyer and where can I get the adapter your talkin about? I thought about weiand intakes. Theyre low priced and seem to work well with mildly modified engines.

you can find a 351w and bump the compression to get a comparable result to a stroker? dont have any charts but in my mind it is basically what you r doing. the same thing anyway. i was reading a hotrod mag that used early heads from a 63 289 to bump the compression in a 302 2pt and then pop in a better cam made for the compression. they breath alright n should give you a nice romping/cruising motor

The 331 Stroker is a pretty good alternative to the 347. Not as meany problems and still pretty torquey...
I've been looking into building one for my truck maybe next year if I get some money back from taxes...

a 351w would be a better way to go for a truck...the 331 ,347 are mainly for those with limited space or very serious about big power with low weight basically a racer...pro street or what ever. you can do more with a 351 than a 302 . iI have a 427 PAW stroker that works really well...
