I'm looking to run around 8# from my vortech strim. I know that the pulleys that come with the fbody kit are: 3.33"(SC Pulley) and 6.66"(crank pulley) I'm going to be running a front mount intercooler with all hard pipe. I will have stock ported LT1 heads with a cc305 cam. Approximately how much boost would I get running the 3.33" sc pulley with the 7" crank pulley??? Or alternatively the 3.12" sc pulley with the 6.66" crank pulley??
