New Exhaust and Dyno
 

Had Bob at FUll throttle install Stainless marine exhaust and retune and Dyno my motors. Best run was 352 HP at the prop shaft, but that was with the timing way advanced, and waaaay to lean. WHen it was finally tuned both motors made right at 342 hp and 404 Tq. Not bad for small blocks. Just the exhaust improved 15 HP, then retuning with the exhaust made a total of 27 HP. Here is a video ofone of the runs. Not too shabby for 383's. Thanks Bob.
