I am looking for a '69 351 engine. I don't really care if it's a W or a C but I am running W now. I want to rebuid it then swap it with the one in my truck now. The main thing I am after is a good block, but would really like to have the heads, crank, pistons, and other internal parts. Any input on where I might find one would be greatly appreciated. Thank you in advance for your help.
