Does anybody know the part number for the primary metering block on a 670cfm Holley Street Avenger. One jet in mine is cross threaded and I think I need a new one. I have searched summit and cannot seem to find it. I have also asked Holley's online help and have not received a response.

you need to get the number off of the choke horn and cross reference it with this chart. It will tell you which metering block you need

It is listed as N/S or not serviced ,does not sound good.

if holley can't solve your problem you probably could use this proform main metering block:
