Well to stroke em to 302 cid, ya need a crank thats 3.70inch, with a .30 overbore. Then of course ya need the pistons, etc. SHM,Modmax,Livernois,and Wynnespeed, all have stroker kits, my guess is just bout any engine builder could do the overbore. (the shm kit is 298cid) To do it another way you can open up the sleeves (bore) to 3.70 inch, with the stock crank youre lookin at 302,303,304cid (depending on how your math is) this one is harder, the spacing is tight, Shm does em by takin out the old sleeves, overboring them, heatin the block, then puttin new sleeves into liquid nitrogen, then slidin the shrunkin sleeves into the swollen bores. give it a final hone to 3.70 inch and youre good to go. this is trickier, I would suggest just gettin the block done by shm, if this is the route you want-they know what they're doin. Wynnespeed, and livernoise have shortblocks, with this same "big bore" however I'm not sure if they are aluminum blocks, or just gt blocks. To my knowledge shm is the only one I 100% know does a big bore cobra block.(aluminum). Wynnespeed and livernoise and modmax all sell a big bore kit with the pistons and bearings etc. If ya have a trusted engine builder! As for the differences, John from shm told me the stroker will give ya better tq, across the board. While the big bore , unshrouds the valves, and gives more hp and rpm. (but also the low and midrange of these motors is awesome. GOOD LUCK, let us you what ya choose. I want to do a big bore block, with some cams,regular boltons. Hopefully in the 370+rwhp range then spray it with a 150shot(for the big dogs) ah someday.
oh prices for shortblocks 3700-5000 range(no core) and the strokers kits are usually in the 3grande range.
