The reason I ask is because the common complaints Eric and Lonnie (2 previous owners) have about my current 350 engine is that the vacuum is not 'quite' right. Hector (friend of Lonnie) measured it and said it did not match what a 350 vacuum should be. Said maybe there is a different cam on it (but I don't think so). Vaccum being off, the 3 deuce set-up has not been working. I am currently running on 1 carb.

Now I also know that Eric swapped the previous 283 Chevy engine (which died on his way to the NSRA nationals in 2002) with a crated 350 chevy. He did the swap while at the show, in one day.

The same headers that were on the 283 still are on my current 350 engine.



I don't know enough about engines yet to know for sure, but by simple logic, it seemed to me that possibly if the headers were restrictive it could create some kind of "pressure"...??

Or maybe I am completely losing it - since i have NO CLUE what I am saying LOL

But just in case I may be right, I thought I'd ask. Is it AT ALL possible it might be affecting my vaccuum, throwing it off just enough to mess things up?
