7029204 Throttle Plate ID

[Greg L.]

Well guys I seem to have myself in a bit of a situation here. I found a date matched 29204 carb about 10 or so years ago and I'm just getting around to restoring it now. The problem I was told is that the throttle plate is wrong(from a 68 SBC). The reason I questioned it is because it has a small block throttle lever which I just recently discovered is different than the big block. The rest of the carb looks correct including the jets, metering rods, etc so what I need now is a correct throttle plate or even one that will work for now until I find a correct one.

My question is how can one positively ID this 396/427 throttle plate assy and in the mean time which throttle plates could I use until I find a correct one? Also where in the heck would a guy start to look for something like this. Whole carbs come up from time to time but this throttle plate might be a little more challenging.... Heck I'm not even sure what P/N to search for this piece.

i'd call all the guys who restore carbs--chuck smith, bob kunz, and anyone who rebuilds carbs in the Driveline. mike

I'm going to assume that you are referring to the throttle body assembly when you say throttle "plate". The throttle body assembly for your application was GM #7036620. Unfortunately, it was discontinued without supersession in April, 1975 and will be very difficult to locate. Q-Jet throttle shafts or levers were never available separately from GM, only as part of throttle body assemblies.

Thanks guys. I'll try Chuck or Bob and see what advice they might have. Since the throttle levers were never offered as individual parts I might have better luck searching for the lever part number in hopes that it is still with it's original throttle body assy.
