Useful linky from the mother ship. http://www.impalassforum.com/vBulletin/showthread.php?t=228114

Too bad this link does not work anymore. Infact it was working friday night. It has been a usefull site for about ten years or so.
http://www.9c1.com/gallery/index.htm I think it belonged to Bob lane back in the day, and has alot of Scott muellers writups and some of the guys from the Black knights out of westford mass also had info there. Sorry to see it gone. I may try to contact capricecars.com to see why they have taken it down.

I have a couple new ones to add.

speed/rpm calculator
engine rpm calculator for this site just use the lower calculator since it allows for a specific trans ratio.

Found another while going through my favorites. A must read for all newbs as well as a great reference set for us forgetful people.
