Mods in sig plus tsp ls6 head and a fast 90/90 with 30lbs svo injectors. Im using arp studs for the heads with a cometic gasket and im going to be intalling the arp rod bolts. How many guys are running 200 and what is your timing set at?

 

Yes. 28* on race gas, 24* on mix.

 

I would consider upgrading to 42 lb injectors.
