yes the 50 Merc engine is all apart, i will still rebuild after this car I have it in my machine shop. I also have a1948 Fathead with low compression in one cylinder. I haven’t had time to inspect it fully; I also have 302 all built but have to take off the windsor heads it was all for racing, I have a set of 289 heads all done I can use. I think I want to install this engine and the c4 in the old merkur Body and make it into a pick up.. if I live long enough, heeheheheh
