Well after talking to some folks that know these shocks and springs I was advised to get the 650lb springs for coil overs supporting an FE.
So Cory you are right to start there. As you said, the springs are cheap enough to buy lighter ones if you have to tune down.
Picked up a set of Ridetechs. Really nice pieces. Will mount them soon.
I had today off so I went over early to get to work on the mounts. To my surprise John already had the trans mount cross bar bent. We are mimic'ing the x brace that is already on the car. I drilled and taped the frame (it's been reinforced with 3/16 tubing). We test fit and tacked, and viola, we had a trans mount. John had to take off for a while so I got to work on fabbing the pieces for the motor mounts. They're looking good but still need some tweaking.
BTW exhaust will go over the trans mount and x brace.
Really enjoyable working at Johns. He's been teaching me some techniques I had no idea about. Learned how to power tap a hole today and use a hydraulic punch instead of drilling. Both time saving deals.
