What are some of you who have enough power to make the back squat and the front end raise( I mean almost take off like a plane) do to limit this motion? I would think that is kind of dangerous. I know I need tires and the back wants to step out, i am being told. Even when I get new tires this seem dangerous because what if you hit a groove or pot hole and it upsets the cars stability. My tuner wants to finish the session on the dyno.

I am in the process of replacing some bad valve seals in my non jet head. I have removed every valve except cylinder 1 intake valve. The keepers seem to be frozen within the retainer. I have the head off of the car and I am using the c-clamp style valve spring compressor but no dice. I've tried cleaning the gunk around the keepers but it is still frozen. The valve seems to be ok and not bent. Any help or ideas would be greatly appreciated. Thanks!

This started getting hot when I was recharging my air conditioner. I seen the plastic smoking a little so I unplugged it. Everything so far in the car still works. Can someone tell me what this controls and why it got hot?     Also what does the blue/red wire control and where does it go to?

anyone have any stock rear housing with spring for sale?
