Looks like what we have here is a pair of ultra rare Ram air II heads if not the whole engine. Can you give me the code on the block?? The exhaust manifolds are 70-71 Ram iv-455ho manifolds. I'll bet the engine runs pretty good! The intake is different for 69-70. The webbing in the center of the intake is closed on 70's. Looks like you have a 68-69 intake. Nice score!
