And yes, while you may not "notice" fuel starvation, that doesn't mean it's not happening. There are rich and lean thresholds that the engine will run under. It's possible that your system provides enough fuel that the engine doesn't nose over, but without a wideband, you can't really tell if the engine is singing WOT at 5000rpm while having a 14-15:1 AFR either.

But my point is that if it's not broke, why fix it? If you wanted to move to EFI, you'd pretty much be forced in this direction. If your intention is to keep the carburetor, there's less of a need here, especially if you aren't having any fuel starvation issues.

And that's the thing. With no O2 sensor I have no idea. Plus you guys all correctly predicted the future with the 18' wheels and suspension. As you now have said, maybe soon I'll have a sniper TBI sitting on top of a Torker II or something like that.
