I used to use Holley 3-422 "Renew" kits, which have been discontinued by Holley and are no longer available. Even the generic rebuild kits for the Holley 4150 at places like NPD are not available (that's what I was told when I tried to order one). What are you guys using to rebuild the 4150s? My carb list # is 3796.

I have a few 37-1537 renew kits if you need one: http://www.holley.com/37-1537.asp

Send me a PM if you're interested. I'll do better than the Holley list price.

Yes, no luck on ebay finding 3-422 "renew kit", which is what I'm told by Holley is the correct PN for list #3796.

I tried Amazon as well and actually found a vendor claiming to sell 3-422. What actually arrived was NOT PN 3-422. Bummer

The Holley specs for the 37-1537 kit I mentioned above confirm that the kit is also correct for list #3796.
