Does anyone know how many CFM the throttle body unit from the early eighties 5.0 flows? I kinda got a weird idea for a project. Does it work with speed density engine (mis)managment?

The CFI units flow about 300-400 cfm and aren't worth crap. You'd pull until about 3000 RPM and auddenly the motor would just fall on its face.

My latest project is an '85 Mark VII that was CFI, and now has a roller MAF HO motor. Trust me, dump the CFI.

on a 2.3 300-400 CFM is plenty, thanks. I got a lot of thinkin' to do to see of this is viable.

You still have the issue of having only 2 low-flow injectors to feed the motor. Even the lowliest EFI 4-banger has 4 injectors.
Besides, I don't know that anyone ever made an intake for a 4-banger designed to use a 2-barrel mount like the CFI unit has.

Yours will be an interesting project.
