You can set the Holley system up using dual TBI units. I'm not sure about the computer requirements of using a stock GM computer with two TBIs. There would be an issue with impedence load of twice as many injectors as it is supposed to handle I know, might be a way to compensate for that without replacing the injectors. That wouuld be the only problem with a TBI system though. If you drilled the intake for direct port injection it would be easier -- just make sure the two air doors are linked together accurately then use sensors on only one. You'd have to do the same using GM TBI units as well (sensors on only one unit).

I know you'd have to weld in bungs for the injectors, but maybe two two-barrel type TB's, and getting a computer setup to match. > > Any thoughts? > > Jim Boone > Mims, FL > > ============================================================= > Posted by wixList Archiver -- http://www.amxfiles.com/wixlist > > > > > > . ============================================================= Posted by wixList Archiver -- http://www.amxfiles.com/wixlist
