What year small block exhaust manifold runs under the spark plugs and dumps out the back towards the ground? I know the 265 dumps out the back ,but what year manifold V8 runs under the spark plugs?I think they came out around 67, but I don't know for sure. I have one for the drivers side, but would like the mate for the pass side ,but don't know where to look.
Thanks guys,Lothar
