400 stroker or 440

I would also caution you that piecing together a stroker package is probably not cost effective. My son will likely build a stroker for his Barracuda. He's run a 383 for years and he's already got a 440 crank (assume for now that it isn't cracked). I already checked into the cost to turn it down to fit the "B" block and get it balanced. Likely cost in the $4-500 range. I can get a kit from 440 Source with new crank, H-beam rods, pistons, rings and bearings for about $1,900. Pretty much a push if you ask me.
