Is it possible to detonate just at idle for a few seconds? The last thing I did before my intake testing was swap my old carburetor on. I tried to start it up and it didnt want to run. Seemed very...

The new rings are definitely seated by now. I am still getting smoke out the exhaust at idle and every once in a while, a big plume on a hot start up. I sent the bore scope down the intake and I see...

I set up the intake and cut .045 off a side. It lined up much nicer. The bottom was crushing the gasket a little harder than the top. So I set it back up today and took a couple thousandths more off...

Can anyone measure how thick the intake flange is on a un cut edelbrock victor dominator? I am just wondering for peace of mind to see if this one was never cut.
