Ok so I have a 04 Monte ss supercharged. Current set up is speed daddy headers, k&n cai, 180 tstat, custom 3' exhaust all the way back with flowtech afterburner mufflers and flowmaster 3" to 4" exhaust tips. No res no cat. Ngk plugs, zzp wires and egr delete. Planning on putting it in a garage all winter and doing some work to race after winter. I want to cam it and drop pulley to a 3.4 possibly even intercooling. My question is, I'm wanting to run xp hot cam. Do I need to upgrade pistons and heads or is it ok to run off stock heads and pistons? Any suggestions or opinions?

 

You should be fine on the stock heads and pistons but you'll have to upgrade your valve springs and get a damn good tune.

 

What # would u suggest for a set up like this that I want? 105? 130?

 

I would think 105 would be sufficient.

 

Just out of curiosity, where do you get the EGR block off at??? havent really looked into it to much????
