To be honest, not sure on converter brand. Got it from a buddy that went to PG instead. He said it cost almost 500.00. But it does flash around 35-3600. I cut 25lb out of the front bumper, converted to aluminum manual brake MC, ditched inner fenders, removed other brackets that were no longer used, and a 25# hood vs stock steel. Gonna try and go scale it soon to see exactly what I lost. 3.73 may happen yet before spring, we'll see. I think between all the changes, and replacing my old worn out hockey puck tires...mid 12's should be pretty easy to hit.
