Jay,
Thank you for the video and info on it.
Back in '71, I bought the MT version and a pair of 3310's for it, to put om my LR, with the Herbert roller but, the MT mounted the dist on top of the manifold, with a extension, down threw it, to hook to the dist gear and oil pump. You had to get machine work done for that and I never got it done to mount it. Shortly after I bought it, I bought my Formula Atlantic race car and of course lost interest in it.
I always wondered how it would have worked. I assume MT relocated the dist to get a straighter shot at the port and maybe better flow. Do you know anything about the MT manifolds?
