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.

Thanks!! Iīm planning not to drill before checking the AFR..also have dual wideband checking!
Just nearly finished with the reworked intake, and bought the carb..and planning to buy some different jets/Pv on the same shipment!
