Broken headers and side pipes.

[Silverback51]

First off, thanks to everyone for their input. It's greatly appreciated.

I dropped the side pipes off to Craig Blood at Blood Enterprises to have them weld them up. He agrees, it looks like it's running lean.

Craig did the initial setup of the carburators, but at the time we did this we concentrated on idle and full throttle setup. Since these are race carburators, that is where they were made to run at. One of the things we did notice during the dyno runs was how much throttle it took to transition from the idle circuit to the primary circuit. I would guess that 60% to 70% of normal driving is on the idle circuit. That's probably the problem. I'm going to have them order some Quickfuel primary metering blocks so we can easily adjust the idle circuits.

So after I get it back together and we get a nice day, I will take back and we will work on it some more for part throttle driveability.

I should get the new headers from Hillbank tomorrow, so I will drop them off for coating after I pick them up. Hopefully we will have a nice day or two in February and I can get this resolved.

Once again, thanks to everyone that replied.
