No they are the same blocks.Where did you get the mounts on the 350 from? The 305 or junk yard?Is it a new 350 or older 350?
NO, They are made different.
Yes they sure are.
You can put in a Chevy 350 motor using special motor mount plates from Summit or any other performance parts place. If you have access to a welder and some time, you could do it. Google Chevy S10 motor swaps and do some research... You can put in a Chevy 350 motor using special motor mount plates from Summit or any other performance parts place.
