has anyone added the unorthodox racing ultra ss pulley set? how did it go and what does it accomplish?
what do they mean about underdriving, and not recomending it?
(see link for what i am talking about)

Worth-while to do??
Anyone added a low temp thermostat? any difference? Made quite a bit in my pops vette.
Also, i know that it has been asked before - but can someone please explain what the plenum spacer does? why is the copper better in snowy conditions?
Thanks for all the help.
G's up!
