Need proof of this...

Good luck on the build Stobin. Looking forward to the results.

I am not a detective to prove anything. That is fact, Google it or read on corvette forums.

Ask any engine builder they will tell you the same about LS7 block being destroyed from detantion, and re-sleeved aluminum LS blocks having issues with cooling system. Besides the LS7 block all other LSx aluminum blocks are cast around the sleeves. Sleeves have to be machined out in order to press fit the new sleeves. During the process when new sleeves are pressed in the, block cracks (hairline cracks which can not been seen) around the water jackets near the sleeve(s) causes it to leak or pressurize the cooling system. If you are okay with that then go for it, just carry few extra gallons of coolant to add in during fuel stops.

By any chance have you worked on or assembled re sleeved none LS7 aluminum block?

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.
