Has anyone ever tried carb spacers on a factory tripower setup? Would there be any hp gain from this?

I have run offy aluminum spacers (1/2") on top of
the cast iron 66 intake to adapt Holleys. Most feel that a "riser" will even out the flow after the throttle blade and will keep the fuel-air mixture from hitting the floor at high velocities but historically Pontiac tri-power intakes do not suffer from that problem as they were well designed by the factory for their carbs.

Just curious, but what about the fit ?
What Holley's did you use to make them fit ? I did not know that Holley made a carb that would fit on the stock intake ? Only on the spacers ? Any modifications ? I'm thinking ahead for the new aluminum intake.....

I used a 440 six pack set of carbs.
I used Offy Holley to Rochester (Large base) spacers. There were no clearance issues on a 1966 Tri-power intake. Tom V.

Tom,
If this combo was tested, what performance benefits did you gain utilizing Holleys on the OE trip manifold ?
