My brother and I are looking to buy a C5 on Sunday, it's a 99 or 00. It'll be his car, but when he goes away for school 9 months out of the year, i'll be stuck with having to drive it for him. Anyway, I know all the difference in years for the fbodys, is it the same deal for the C5's, as far as the differences in intake manifold, cam, etc. between the 01-00-99. I know it's pretty much the same car in terms of the engine. Also, what are the first mods needed on the C5 anyone know about the stock intake and exhaust.

 

You would probably have better luck on LS1.com or LS1tech.com for some good in depth answers on what is different

 

hey mike let me know when you get it. maybe ill have better luck against that... j/k
