GPS... No I had my truck up there, returned some borrowed slicks. We looked at a impala convertible that was too rusty.

Yes, Thats the one. It works great. It has a very slight bog off the line. All six barrels opening suddenly is hard to overcome with an automatic.

I got a walk around video of the car. It is a real 442 with factory gauges and tach. Right now there is a 3.31 12 bolt posi in the rear. It has a 455 and GA heads. A mild cam and I believe a 2500 stall. It runs and drives real nice. My son painted it a couple years back.

It may not be the automatic. I suspected the accelerator pump shot and went to the intake thread and looked at your setup. You have the accelerator pump rods in the wrong holes on the end carbs. Move them to the inner holes for a bigger pump shot. Beyond that, what jets are you using vs. what camshaft? Stock jets are lean. As a starting point, you want at least 64 primary and 71 secondary jets. More rear gear would help too, of course. Mechanical secondaries are less forgiving than vacuum which restrict secondary flow until the engine can "use" it. My setup id different but I get no bog, and I have run Tri Carbs since 1973 in a number of setups without that issue. Hope you get yours running right.

I think you may be right about the rod locations on the tri carb. I found a picture of a tri carb intake we had many years ago and it worked perfect. You sure know the tri carb manifolds.
