I am running the stock 3T GTE cams at the moment - I have not yet measured the duration and timing differences to see how they compare. I say suck it and see and then tell us the results (ideally you would do back to back power runs and overlay the graphs to see where gains/losses are made).
Jesse - what is the exact duration of the 3T GTE cams and the 2T G cams? I am pretty sure that the 2T G has had about 3 x different factory cam grinds during it's evolution.
