hey man. nice run, nice car too. you should also check out our local forums New England Pontiac Enthusiast Club :: Index

may i make a few suggestions?

switch to copper plugs ( autolites)
get rid of the TB spacer, no benefits, just blocked coolant ports
and if you wanna go further into modding the car then you should get some headers. they are on ebay for ~$200. and yes theyre good. if you dont want to go the header route then maybe look into a Plog or PEM.
