I didnt get flow sheets when heads came back from Tony Mamo after Bob M had me send them to him (was 2 1/2 years ago) , I did get them in a email but cannot find it now. I will post up pictures of the intake though. After fuking around for past 20 minutes trying to get pic to go thru I go to advanced settings and see until i renew my gold membership its not going to let me post pictures, going to bed.

I can't wait for the further changes. Exhaust, cam, induction, and so on. You rarely see this kind of development being done. We can protest our theories all day long, but the proof is in the pudding . Thanks for sharing your project Smitty.

The above pics, first one is port openings of Chinesium intake vs edelbrock victor, gimme fuel on here borrowed me the victor to try and he previously port matched it. I port matched the speedmaster and opened up the 2 tight ports i mentioned before, the writing you see on the face was widths/heights of ports the best i could measure them at pinch point. The second pic is bottom of the 4150 carb, dominator adapter and phenolic spacer. 3rd pic is dom sitting on Chinesium intake

It be cool, if you had an IAT sensor in the intake . I'd be willing to guess, the IAT's would be a fair amount cooler, with the carb, over the port injection. Especially when the weather heats up a bit in michigan. I remember reading a test where they did this on a Pontiac engine. Carb to port efi. The carb made about 20-25ish hp more if I recall, and the intake temps were quite a bit lower in the plenum, compared to the aftermarket port injection setup. It was like a 500ish hp build.
