Default Governor Spring?

Is anyone here running a 4200gsk, if so how do you like it and where did you find it? I'm getting 60# valve springs anyway. Thanks in advance.

I have one in our 1st gen but to tell you the truth that after 3200-3600 the VE pumps dont make any more power so spinning 4200K is just flowing hot air and making alot of noise and wherein out your valve train faster

So basically it's wasted money, and it would be better to get a 366?

I would highly recommend a 366. I put one in my truck and it makes a world of a difference. You probably still wont be able to fuel up to 32k but nothin a new lift pump cant fix

Yeah that's what I'm going to go with, and I plan to get an airdog II one of these days so that'll cover it.
