![]() Simple topic, but I wanted some additional input. I finally got tired of my demon-possessed Holley 850 and purchased a new Holley 850 with the aluminum construction (about 5# lighter also!). The old Holley center stud is 1/4", while the new carb stud size is 5/16". I'm not interested in drilling out the perfectly good looking OEM lid to 5/16", and I also prefer keeping the stock look of the original 1/4" wingnut. My first plan was just to weld a remnant of a 5/16" bolt to the remnant of a 1/4" bolt (the heads are sawed off both bolts), but it may or may not be a PITA to get the two different size bolts lined up to the same centerline prior to the weld. So, I thought perhaps I'd just get a 1/4" coupler nut (if that's the correct name), and then drill and tap one end for a 5/16" stud that would go into the carb, and thread in a 1/4" stud in the other end that would protrude up into the filter lid. I've got a few more days of being tied up moving stuff from the old house to our "new" place, so in the mean time I thought I'd ask if perhaps there's a simpler or more elegant way to get a 5/16" thread on one end and a 1/4" thread on the other.
Thanks for any constructive input. |

![]() What you suggested, or just drill a small rod each end for threaded rod clearance and weld them in. Or, put two hex bolts head to head and weld them together. I welded mine, as having a bolt back out and drop in the engine is not for me.

![]() Or- get some 5/16 threaded rod- turn it down on the end and die it to 1/4
the easiest- buy one of these- $2.50 and add some 1/4 threaded rod Allstar 26058 Air Cleaner Stud Adapter - 1/4-20 to 5/16-18 in Thread - Steel - Zinc Oxide ![]() |
