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!

NMCa still uses that in the rules for NA10.5. Seperates heads in to categories for weight based on distance off the deck. As well as a few other things
