Holley Base Plate

Post by tankin » Wed Nov 30, 2005 2:30 pm

It's funny how the venerable Holley has almost gone extict. Try as I might, there are no good used examples to be found in my area.

Does anyone have a line on where to get a good used square bore base plate, or carb for that matter? I have found plenty of new pieces online, but they are almost as expensive as a complete carb.

I believe a 750 base plate with 1 11/16" bores is most desireable since it is closest to the size of the Impco 425.

Thanks in advance.... :?

A friend came through with a Holley 600 cfm cheap enough that I snatched it up. For future reference, it is an 1850-3 model 4160 with vac. secondaries. The bores are 1 9/16". They are slightly smaller than the bores on the impco, but look to be just fine. The 1 11/16 bores on a 750 cfm base are probably a closer match, though.

Frank & Franz, Look for a question I have in the tech topics about the secondary acctuation. Thx.
