Can any body tell me what I need to buy from IH north to billd a 392 out of a 345 like crank shaft/pistons/con rods?
 
A 392 cannot be created from a 345. They are two separate engine blocks. The cylinders in a 345 can be bored, but even at maximum the displacement will be under 392 cubic inches. Assuming you have a 345, just what is it you are trying to accomplish?
 
Ty for the info. Im in the midle of rebilding my 345 & I thought I could bilt up my 345 to a 392. But I have to smog this Scout its a 1978 so im just going to fix this motor and bild a new 392 later. I just need to get my new Scout back on the road so all my freeze plugs were leaking. So I pulled the motor apart and found the cam bearing were gone so im doing a full rebild. Ty for all the info now my job should be easier now
 
Also, the 392 uses a different head, because the diameter of the exhaust valve stems and valve seats/heads are larger diameter than the 345, 304, 266 exhaust valves.
