Eric, I've just finished putting some ProJection info on my automotive
site

	http://www.austin.cc.tx.us/ESA/tc_auto.html

(see first link at top)

I, too, would like to "re"-find the site on the Holley ProJection ....
anyone know where it is ??  It was done by Andy Quaas <mpc at genevaonline.com>.
Don't have any web info though (musta lost it).
