I have sets of square port heads for 1966, 68, 69 and 70 along with 68-69 396 4 bolt blocks. I also have one set of 1967 tripower carbs, 68 427-435HP tripower intake, 6223 steel cranks, pistons and dimple rods along with two 1970 #4492 factory L78 and LS6 carburetors as well. If you have any interest in these parts you can reach me at 330-770-2517. These parts are in excellent overall condition and they are not cheap. Thankyou
