After an embarrassingly long time, I have finally finished the BBC port injection plenum. Engine is a 502 and the intake or base for the plenum is a modified RamJet. This is going into a 68 Corvette with a stock BB hood so I was really restricted on height at the front of the engine.
At this point I have the engine mounted in the rolling chassis (body off) and am plumbing the fuel system. 1st pic is CAD model, 2nd pic is mocked up right off the machine, 3rd pic is in process and last is assembled engine
