Carb spacers have been around for YEARS. My grandfather was making them for old flatheads in the 50s. They do work on some engines, but don't really do much for a stock engine.​

Yes, it's not a new idea, they've been using them for yrs, but they only work on carbed or TBInjection. I'm looking for some extra grunt for my recent 95' V6 S-10 pickup for towing. Low end isn't bad, but it runs out of breath at 40-50mph. They used this principle on the old 63' Dodge ramcharger 426, it had a hot cam, then to recover low end torque they gave it a ram effect long runner intake manifold, but it also helped all through the rpm range. Along with this, there is also a seperate injector spacer to raise the injectors up a bit out of the airstream, that also helps, it's at the lower part of this page:

Here's the theory behind it:

Don't expect much difference with that type of fuel injection..
All your throttle body does is allow air in...no fuel like the older TBI motors.
It would make a better door stop...:rolleyes:

Gary, My recent 95' S-10 has TBI, it has 2 injectors right on top, it mixes fuel, & air, so it will work, it's not port injected, CFI, nor CSFI.
