I am running a inline 250, T3 turbo, blow-thru Holley 2300 350cfm, 10 psi max., HEI, AEM wideband to monitor

I drilled my pvcr's to .078", jets are at 61 and PV at 8.5.

If I had to do over again, Do Not drill out your pvcr's and jet accordingly. If your AFR's are too lean at WOT, drill them out a little bit.
