After sorting this all, I ordered some 7/16x.168" straight-wall pushrods from Manton with .040 restrictors. I had an intake manifold flange from my buddies 1400HP single-4 565" BBC and laid on the deck-surface to gage why his makes so much more power than my 440-1's (in the background)
The old NMCA Real Street class rules used to have a weight adder determined by how raised off the deck surface the intake port floor was. Thought that was a pretty clever way of trying to even things out. Looking good!
