C2orC3Tripowerquestion

[Guest]

I have a 67 427/390 IQ code car that has a tripower set up on it (400 hp conversion). This is obviously not correct for the IQ code. I need help to determine what the tripower set-up fits and what year it is from. Here is the data:

Intake: GM 8894382
Carb: front & rear: Holley 3659 center: 3888
Date: 1200 on front and rear and 1509 on center.

These dates don't look right but that is what I copied down from the front of the carb. Can anyone tell me what it means?

Thanks, Steve

Steve -

The 4-digit date codes say the carbs are post-1972 service replacements; the end carbs are late April '80, center carb is late May '79.
