David, I went out to look at the intake and I don't see how I could put it on wrong unless there is a left and right that is different. The bolt holes are different and would not allow me to put it on backwards but I am still listening. Is there something else that could make it possible to put them on wrong.
Gus68,
I was planning on asking someone from the rebuild shop to come over and listen so I am not trying to explain what the sound was.
TA69vert,
I am running the lower octane from the local station, nothing special but it is not drivable yet just started it up for break in a few months ago. The exhaust leak that I am trying to figure out coming from the choke area on the intake is loud, like open headers, and I am going to block that off so I can hear the sound better.
As for the Chebby engine, If I had it to do over again that is what would be in there, cheaper to build all around and I know how to work on those.
