For someone restoring a HP 352 car the correct engine would be quite valueable. These were the first true HP engines. I'm not sure if it would be a solid or hyd lifter block but easy enough to tell. I'm also not sure if they had a oil pressure releif valve like the 390HP, 406 and early 427's. Take a look at the back of the block at the cam plug area. Other than a 4.00 bore and 3.50 stroke I really don't know much about the 352HP. I can tell you if the castings numbers from the heads, crank, rods and such are correct for it though. G.
