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. http://www.holley.com/data/TechService/ ... isting.pdf |

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. |

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. |
