12.5" Power Valve??

Anybody know of a source for Holley or Quick Fuel 12.5" power valves? I have seen them mentioned in some articles, but can't find any for sale.

Good luck. It’s getting hard to find anything with a sinner opening than a 10.5.

You can try BLP and see what they have. Or Braswell.

I have a 9.5 in mine and could probably use a 12.5. My cruise vacuum is around 14hg.

Yep, I have a few of those. Just wanting to do a little more experimenting. I have a couple of cars that have a cruise vac of 16.

Remove the spring on a 10.5 and slightly stretch it.
