Jet size for a Holley on a 351?

I am gonna have another go at getting my 83 to pass smog. I believe the PO installed different jets to compensate for a bad vacuum leak. Now the that the leak is gone its too rich.

My question is does someone have a holley 2BBL on a 351 that passes smog AND knows what main jet size they are running? I guess there are secondary jets also, that would be great also.

I know there is a procedure to obtain the proper size, but if someone has already done it or has a ballpark idea that would be great! I am on a tight budget and don't have a vacuum gauge. The jets are like $8 a set at Kragen here so I would rather not play hit or miss!!

Thanks for any help!

Mike.

Call Holley Tech Support. Those guys are very helpful. Tell them your set-up and they should be able to get you in the ball-park over the phone for free.

What state are you in, anyway, that smogs an 83?
