New Build Startup Issue

Teeing the PCV together with the booster is gonna make the back cylinders idle lean. Good luck tuning that.The PCV should be running to the front of the carb, and entering the intake thru a channel provided that will mix transfer-slot fuel into it, and hopefully every cylinder will get proper AFR.

> If you have a big cam, I recommend not to run the booster off just one intake runner. Pressure in the runner, at idle, can bounce to the positive, lowering booster vacuum, and depending on how sensitive your booster is, it may not function.
>The booster should always be evacuated into the Plenum, all by itself, so as to minimize idle fluctuations when cycling the brake-pedal.
>If you think you might have timing problems then make sure the Powertiming is not more than 34>36 until you fix it.
> I would drive it with just the outer springs for a few hours, but keeping the rpm under about 4500. During this time, I would set the idle speed kindof high, and I would idle her as little as possible.
