Thanks, that wont be so bad on the suspension as the LS1 I am going to put in is 390 lbs.
 
What is your plan for your old Duke? If you were just going to get rid of it, I may be interested in giving it a new home.

I dont know yet but I wont be able to start the switch until May.

I just put a note on my calendar to check back here when I pull it out. it only has about 7K miles on it as the PO put this one in, it was a crate motor.
 
I just sent you a pm.

Keep me in mind if and when you do decide to part with the duke.

Good luck with the LS1!
