Jeremy was kind enough to send the carbs to me for evaluation. I have disassembled these carbs. Jon is correct--the center carb is an Old's Rochester 2G. The front carb is a correct '64 thru '66...

Front carb looks ok. The rear carb is toast, except for the base. Center carb may be OK, but the airhorn web may be warped. That can be fixed if it's not broken.
I'm confident all the bases are...

Myserious Bog
A friend in Green Bay, WI has a '64 Tri-Power GTO with a stock 389. It's a 4 speed car.
He called me this week with a story that is hard to believe, but he is ready to show me in person--he's...

I agree. Set the hydraulic lifters with the engine running.
Very simple--adust the rocker nut until you hear clicking from that valve, then adjust the nut about 1/2 to 3/4 turn beyond where the...

Tri-Power setups obviously have three needle/seats. Quadrajets have one. Holley's have two.
At full throttle, isn't it logical that the three fuel inlets allow more flow than any single carb? I...

With that cam, it is necessary to have holes in the center carb throttle plates. That allows the idle stop to adjust the throttle blade opening so the idle circuit functions properly. I have never...

I set all of them to the lowestr tension hole (the front hole). If your throttle sticks, there are other problems that need to be addressed. Driving a Tri-Power or four barrel car with too much...

The OP noted his engine will have a hydraulic roller cam and 459 cubic inches. He's aiming for 500 hp, which means the cam will be fairly radical.
I've restored Tri-Powers on many Pontiac engines....

If your Tri-Power ran well with the 400 engine, but you're going to 459 cubic inches and a healthy hydraulic roller, the carbs need to be calibrated to work with that combo. If you provide cam specs,...

I don't think there is a source.
When I restored my '64 post car, I tried several vendors, including salvage yards with no success. I ended up using the original channels, which had very bad...

Non Pontiac (Corvair) Carb Part Needed
I foolishly agreed to rebuild a pair of 1964 Corvair one barrel carbs. The NAPA kits contain accelerator pumps, but without springs and retainers. One of the pumps in the two carbs is missing the...
