intake port molds - ZR-1 Net Registry Forums

Got the port molds done. Pretty neat to see an LT5 port from the inside out. Also helped me confirm the cross-sectional areas.

here are primary and secondary head port (right), and also primary and secondary injector housings (left). Pay no attention to the lengths... I didn't get a "full pour" on a couple of them. In this pic, you can't see just how unfortunately large the bowl is behind the valve, as cast. We discussed seriously about welding that or using some epoxy to reduce the volume there, but didn't do it.
