Is pretty bad on this set up. #7 pig rich. #1 leanest.

I`ve never had a flat bottom intake , mine were always tented.
I`ve had 8-71, 10-71, 8.3 Whipple and none were thi sbad.

The blower is a TBS Retro Hi -Helix 14-71 with injector plate.

Does not have a delta opening .
Im thinking of getting the intake I used to run but not sure if that`s the issue.

Open to any experiences .

Quick sidetrack for my knowledge. Those plugs conewith a .031” gap. What do you gap them too on these engines ?

Are you running Boostane? Those orange plugs look familiar to when I ran Boostane in my 8.1 truck.

I leave the gap the same .
Yes I`m using Boostane , turns the pugs orange .

I have a few ideas to fix this .

I wonder if anyone makes a "spider" for the bottom of that intake like the Nascar engines used to use
