Holley 94 thread and jet question

Can someone please tell me the thread on the vacuum port of a 94 Holley as I want to block it off with a suitable plug.

Also any suggestions on a start point for jets & power valve to run it on a stock model A banger motor?

thanks

 

The thread size for the vacuum port is 3/8"-24. A good jet starting point would be 39-42. A 65 power valve I think will work fine.

 

Thanks dickster, the jets currently are 59's with a 65 PV. I'll order up some smaller alternatives.

As a second thought, i bought a pair of 94's with the secondary carb minus idle circuit and choke. If I get a Y adapter from charlie price how would i jet the pair? or would one realistically be better as a dummy on the stock banger?

thanks Vince

 

Vince, I might be critisized for this answer but I would try one hot and 1 dummy to start with on the stock 4 cyl. I think you will overwhelm that little engine with 4 times the fuel all at once. If it runs good on one maybe include the 2nd one but I would suggest on progressive linkage so you will have some RPM's going before you dump the extra load.
Actually, I have one of the adapters you are speaking of in stock. If interested PM me and we can talk.
