Holley Help
 

Like an idiot, I cut the horn off this Holley and over the last 20 years have lost the peice with the number. It had a GM number on it, and best I can remember it was suppose to fit a 70 454 Corvette Auto.

I can now find nothing on the net with a set up like that, nothing in our old parts catalogs, and nothing in Holley's books.

Can anyone point me in the right direction to make the best guess at ID'ing this. The purpose is soley for my on satisfaction, and to redeem my stupidty.

OH, and it is a 780 to the best of my memory.

The front meter block has a 7091 and 62381 on it.

I also think the GM number was 7 digits and started with a 3.

If I'm not mistaken, a 70 454 Corvette would only have a Quadrajet since there was no LS6 that year.

Re: Holley Help
 

If the second number on the metering block is 6238-1,
then I would assume the carb was a LIST 6238.
Also check the front right ear on the baseplate. The carb LIST number should also be stamped there on a service dated carb.

I don't know the GM part# right off the top of my head.

carb is pt# 3997788-GB, list # 6238-1 (LT-1)

Just found it.

You're right,that's a 1972 Camaro Z/28 350/255HP Auto.Trans.application.
These originally came with a #6825 Front metering block.

Listen guys, I want to thank you so much. You have no clue how much this has nagged at me, I feel like a moron for cutting it off back then and for losing it.

It does have a 62381 with no dash on the base, and I vaguely recall the GM number ending in 88. But how does one know for sure after all these years, heck I have trouble remembering my kids birthdays.

One thing that sticks on my mind hard is that it was for a Big Block auto car, is there any chance I could have the year off and it was on a 71 that could have been a 454?

Re: Holley Help
 

Only List #'s I see for a 71 BB or 454 would have been #4802 or #4803.
I see nothing connecting it these numbers or those engines at all.
