Well I have a 6.5 HF broke it in and at top speed I'm sure I was going 40-50 because I was passing up cars on major streets in Los Angeles, but anyway I hear about t his governor removal and how it increases power in the motor so I went ahead and did it and hooked up a new throttle system for it fired it up and now I'm going slower? don't understand why, I just bought a 2 stage pipe for it as well, let me include that the can did fall out while removing the crankcase but I am positive I realigned right and also one of the pushrods fell out into the block where the cams are but I put it back inside from the rocker arm side, valve lash is set .003 exhaust .002 intake just including anything to get a better idea I would really appreciate the help guys thanks
