he has a carbureted Camaro... those had so many extra vacuum lines, and lots of other useless stuff on it. if any of those vacuum lines are cracked and brittle, soaked with oil, or ended up in the wrong spot over the last 17 years, it might be doing more harm than good. then factor in an EGR valve that may or may not work right, along with all those temp switches in the vacuum lines, and you have trouble.might be easier to get it to "look" stock, and tune it as best as he can, and see what happens, instead of spending maybe hundreds of $$$ on the "correct" smog stuff.
all i said was to make the basics work right- vac advance if it has it, PCV. then go from there. i have seen quite a few 80's GM products that ran like crap until all that stuff was eliminated. i swear,GM must have gotten a good buy on bulk vacuum lines during that time frame. i follow the KISS rule- Keep It Simple,Stupid. the less clutter, the better. and i bet the tailpipe sniffer would agree with me, if not the un-informed EPA and all the greenie groups out there- but i guess they are the only ones that matter.
