Re: Easy Horse Power upgrade?
Is this a Z car or an SS? I thought the anniversary car was a special edition of the SS, red with silver stripes. Does it have the factory hood scoop? That's how to tell the 315 hp SS from the otherwise similar 305 horse Z28.
First up for upgrades is the exhaust system. Put headers on and a true performance dual exhaust. Then install a hotter camshaft and while you have it apart install a low temp thermostat. Then go look for a shop who can tune the computer to make use of these components. By this point an aftermarket air intake should be on the car too. With the right parts these engines can make 400 hp.
