Sorry for the misinformation.

Today I also check my engine timing, is set to 5° BUDC.

Thanks for the update James. I did move the distributor to the manifold vacuum. I think it just has constant vac now when driving. Did okay hauling tractors yesterday...

I'll move it back to the carburetor. That port on the back of the Stromberg had no vacuum at idle so I'll have to check and see if it does when throttled like you said.

Re: Upgrading to HEI on the 5000

Somebody ( PontiacJohn...?) sent me money last week, via PayPal, for the Buick V6 distributor bushing, but I never received a mailing address.
Does anybody know "PontiacJohn..."
He is not replying to my e-mails.
I am ready to ship the parts, but need an address.
