I have a 1985 K10 Silverado that had a 305 in it. I am assuming it was the stock motor as it had very low compression. I purchased a used 350 that came out of a old Chevrolet Winnebago. Ended up being a good low mileage 4 bolt. So got it all cleaned up and put into the truck. The transmission I assume is a 700r4 as it has 16 bolts and MD8 on the side of it. The problem I have is now that it is in the truck and the transmission is mated with the engine, my torque converter/flex plate bolts do not line up. I am assuming that the Winnebago it came out of had a much larger transmission. THe bolts are off by 1/8th of an inch or maybe a little more. I have spun the flywheel all the way around to check each hole. I still have the old stock 305 that I pulled out. Can I use the flex plate/flywheel off the 305? I am confused on the entire internally/externally balanced or how to know if this is something that is going to cause problems. I did notice that on the 305 (old motor) the flex plate has holds partially drilled into it in a straight line. Not sure if this means it is balanced to the engine of just a balanced flexplate. I may be overthinking this but I appreciate any help. Thanks.
