i have an old style 350 4 bolt main. i think the casting number is something like 3970010. i'm asking $100. it needs machine work. i would bore it. should be .030 now. 0.040 should clean it up. i always recommend decking anyway for any horsepower. will have to pick up or i can deliver within reason. i will take the best offer becuse i've had this block for a long time and i don't think i'm gonna get around to using it. just send a pm with your offer. i can also send more pics. i take paypal. thanks...
