hey all i got a 4 bolt main short block core for trade. i would really love to trade for a stall converter for a 85 700r4 about 2100-2700 would be nice.but if you dont have that a headman y-pipe with ball flanges i could use a flow master muffler maybe a set of gears 3.42 or higher. or outher motor stuff just get ahold of me and we will talk. oo yeah the block has flat top pistons and crank. i was told it it ran when it was pulled it just got left out side it the rain because the guy that was going to buy it stiffed my friend after he pulled it and told me to just take it because it was in his way. i live in springfied ohio
