Tripower intake power vs 4barrel
Hi, has anyone done any dyno testing or drag strip testing on the 1966 tripower intake on a 400-455 versus an Edelbrock performer or any other intake?
Right now I have a Edelbrock performer and an 800 CFM Holly spread board on the very mildly built 455 in my '67 442. I'm thinking of putting a tripower off of a 66 onto it because I like multiple carburetors. I don't want to hurt performance though.
Thanks, Joel

Years ago I had a 65 442 with a 455 .030 over bored with an JM 22-25-10 cam. Originally it was built with the tripower installed, later I installed one of the old style torker intake with a Quadajet carburetor. I never did any dyno time with it. However I can say that driving the car was fantastic with the tripower with the 3 different options that you had with the carburetor setups.
The reason why I changed was the center carburetor was just worn out. Driving with the torker was okay but no where near as exciting as the tripower. Not to mention the comments that you received at car get together. It's surprising how few still don't know that Oldsmobile had a tripower in the 60's.

As has been said already, the tripower was totally the WOW Factor when people see it on an Oldsmobile. The option of having different controlling rates for the end carburecarburetors was incredible and the way that the engine would respond is something that I will remember forever.

Very true about comparing, however at the time I had both intakes and only had a limited amount of time to swap them out due to work. For the jetting we had to increase by 2 sizes. As I said the only reason I changed it out was because the center carburetor was totally worn out. I still have both intakes however not on any engines at the moment.

That is exactly what went baw. Back in 1986 is when I was forced to swap the intakes out. There was nothing available then. When I retrieve the intake from California I will hit you up.

Thanks for all of the helpful replies! Sounds like I can put it on there and at least not lose any ground, and have lots of fun.
What wears out on the carburetor bases? Is it the throttle shaft bores? Years back I remember a local carburetor shop with bush them.

They normally don't wear that bad but as with anything it can wear. Tell me what was worn out on your carb.

Many years ago Pontiac Enthusiuast magazine swapped a Tripower onto a 428 powered 68 GTO to compare it to the Rochester 4bbl and Pontiac cast iron intake (which is supposed to be very good, nearly as good as the Edlebrock RPM). They picked up 2 tenths with the Tripower over the Rochester which translated into 22 hp.
Remember: Pontiacs have Tripower. Oldsmobiles have Tricarb.

On mine it was the carburetor base plate, idle screw threads in the carburetor base plate were worn out, the throttleshaft had grooves in it and the bore in the carburetor base plate for the throttleshaft was oval and out of round. At the time that I had it on the car, nobody was repairing them. I kept it figuring that someone in the future would start making or repairing them.
