craig71188 Posted June 28, 2014 Report Share Posted June 28, 2014 Factory GM TPI set up including fuel rails/injectors. Runners have been ball ported (plenum & intake ends cut then large steel ball bearings pressed through to stretch the runners-opens them up to about the "as cast" size of many "performance" runners), lower intake received a minor clean up and plenum was opened up. Sorry, no pics - looks like a stock TPI from the outside. Asking $100 for everything. Link to comment Share on other sites More sharing options...
