Did some more work on the intake manifold yesterday and today. Getting closer. I welded on a plate to the back side and the throttle body mounting flange made of 3/16" steel on the front. Not seen in the pictures are three 3/8th NPT threaded pipe/bungs welded to the bottom side of the outer shell that I can thread different sized nipples on to use as vacuum ports as needed. Tomorrow I hope to cut and drill out the fuel rail so I can make the fuel rail hold downs. After that a coating of epoxy over the welds and then paint
One thing now with the laid over fuel injectors is the fuel rail won't interfere with the OE water outlet if I decide to go back to the stock water pump system it'll work.
Cut and drilled the flange for a nice fit with the throttle body I have.
I would of liked more plenum volume, but this is what I have to work with on this version. I welded and formed a small piece of tin on the left behind the throttle body to try and keep the air flow from hitting the flat side of the first runner.
