Those spacers look nice. A word of warning on your fuel rails though. I had a similar setup with the fuel regulator mounted to the fuel rail. The extra weight of the regulator caused the mounts on that side to break in some very rough water allowing the the injectors to come out of the manifold. This happened to me twice before I made some mounts out of stainless steel, the original mounts were made out of aluminum.

Great thread.
imho/e the tb spacer bottom should be same as intake manifold top.
Top of spacer mounting surface same as bottom of tbody mounting Surface.
The transition from the two is grad as possible.
All of this not as important, but can still help, as it would be as a carb or tbi tbody, because no fuel in this area to get stuck too.

Carbon fiber reinforced PLA. It has a higher heat deflection temperature than basic PLA. Also, I've had a piece of this material sitting in a jar of gasoline for a month with no ill effects. I know gas won't be going through the throttle bodies. I printed carb spacers previously out of PETG.

Rookie, how many LBs per hour do your injectors flow?

I bought 80 lb/hr injectors. A little on the large size for my engines, but if I added superchargers at a later date I did not want to buy injectors again. Smitty and I discussed this before I purchased them and thought this would be the best route.
