8679 looks to be a 650cfm carb, but I can't see a listing for the 4574. There's a 4575 which is a 1050cfm carb.

Here's the Holley Carb numerical listing for future reference.

The 4574 is a 2bbl

Thanks!

I did see this 650 is a Qjet replacement.

That numerical listing looks to cover only Holley's aftermarket carbs, not any of the OE units. I have the big master OE number book, but it's buried somewhere in my disaster area of an office. Fortunately, there are ways around that sad state of affairs.

A Holley #4574 is a model 2300 2bbl originally fitted to 1970 International-Harvester trucks with 304 V8 and manual transmission.

Too many people who were born on third base actually believe they've hit a triple.

Thanks Dan.


Just wondering if it was a 500 or 350. It is in pieces. I may have enough to assemble it.

It was in a box of Holley stuff I was given.
