Hi Don,
Yes the diameters of the new tires are a little different from the old 
tires.  The shorter rear tires have put my acceleration back into the 
"warp speed" category even with the 3.77 rear end.  According to the 
calucations the difference in rpms at 60 mph was like 160 rpms more 
(or something like that).  At any rate, the acceleration is noticably 
quicker.  The handling is improved but I am in the process of "pricing 
out" a Quaife limited slip rear end to help keep the rear end "hooked 
up".  I am still playing around with the spring rates in the front 
(225 lb)and in the rear (150 lb.).  I am also going to change the 
anti-sway bar diameter from .690 (approximate) to .875. So, I still 
have a ways to go before the suspension is fully sorted out.
I'll post some pictures when I am a little further along in the 
progess.
