Thanks for your help cobalt

It's not a vortec engine I confirmed that using the number stamped under the valve cover. The person who sold it to me had said it was a vortec engine when I bought it but I had no idea how to check that at the time. Anywho, I know that swirl ports don't make good top end power as they are made for pulling/towing/hauling hence the good low end power. I've got the computer controlled distributor and every now and then the engine light does flash but not for very long. And I do have the Y configuration you mentioned so now I ask is there a better way to get vacuum? Where can I get a single full time vacuum source off the manifold?

The tranny I have now is a fresh rebuild i bought from summit racing its not that POS I bought off the street I was having issues with :sweat:
