So, here it is in! I think I have about 5 hours in it including removing the old stuff. Assembly is easy, slides right together. I did have to be careful aligning between the pipes and transmission rods to make sure nothing rubbed. I did a bunch of changes at once- HEI ignition (SSD style), replaced both manifolds and went to 2 barrel carb (BBD) and the exhaust. The difference is kinda shocking! Way better acceleration and smooth all the way thru the rpm cycle.
