Default LS7 Swap

OK.....moving on. As for the suspension, as 77 CA mentioned the A/G cars are very similar to the F-body and do share some components. I do not run a drop spindle on mine, just the QA1 set up. It allows me enough room to reduce the height and can be easily disassembled to change springs if needed. The main concern with drop spindles would be bump steer issues if the suspension does not have enough travel. 6-Grrr, I am going to continue to run the TKO/600. It would be nice to get the 6-speed in the car, but I really dont want to have the expense right now.

I have decided to tackle a another project since the car does not have the drivetrain installed. I have purchased another '73 GA frame from a local wrecking yard. It is perfect and has no rust or previous damage. The reason is I want to increase the frames strength and rigidity. I am delivering the frame to a local chassis shop called No Limit Engineering. They are going to redo all the frame welds, box the entire frame, add cross bracing in specific areas and then true the frame to make sure it's straight. It is as much as I can do without going to an aftermarket frame which I can't afford to do. I will then powder coat the frame as I did with my original frame. This allows me to improve upon my original frame, and then swap everything over all at once. So I will be posting pictures of this entire process as I progress. I am hoping to have the frame finished by November, and the entire LS swap installed before the end of the year.
