Just buy a motor from ATK, I got a 351 long block with performance cam for $1500 or $1600 (Including shipping) I forget now. Motor ran perfectely and stil does, I put 20,000 HARD ABUSE miles on it, its either on the floor board brakes or gas every second it has ever been driven or doing. Actually it has broken SIX rebuilt performance transmissions and the motor hasnt even needed a tune up (And thats on only 32s). And if you look at there website they have pretty much the best warranty you can find, and hassle free. Three of my coworkers all have bought motors from there up to a built 460 that runs like a scolded dog down to a 302. But if you want to get a local shop to rebuild it feel free, but warranties are hard to come buy through them some times.
