i just bought my 05 SS/SC and the dealer told me the previous owner did a lot of work under the hood.. i know it has a front mount intercooler/intake and exhaust how could i find out what else was done to the car?

[cobalt123]

take a good pic of the engine bay for us...,

check the supercharger pulley, it should say what size it is

[BlackMagik]

there is i think 3 pictures of the bay on my profile check it out, and tell me what you think

[cobalt123]

well the i cant see the pulley much but it doesnt look like the stock pulley

if its smaller than 3.43 in then the car would need larger flowing injectors both of which requires a tune

the intake is for sure not stock, and like Bryan said, the pulley appears to be not stock since its yellow... or at least appears yellow in the pics

or for some odd reason, the previous owner might have painted the stock pulley... but i dont think thats the case. lol

not to familiar with the LSJ's but isnt an obvious way to tell if the pulley has been changed is by the color of the bolts?

[cobalt123]

yes stock pulley is pressed on smaller pulleys like the gm stages have blue bolts
