Cams and Heads are on
Well finished my ported heads and cams install, drove it to work and it runs hard, the heads were ported and new big valves installed by BoPort racing in CA, the cams are SPR stage 2 (127500 comps) other then those two things the car is bone stock, stock intake, stock cast iron manifolds stock exh.
I'll know more tonight when I put it on the dyno, the butt dyno says it lost just a little on the bottom and gained HUGH from 4K up... I'll post dyno results later tonight or tomorrow, stay tuned, coming soon will be dyno results for Extrude honed stock Exh manifolds, then intake.....

Well I put it on another Dyno just to make sure the tune was ok, my car based bone stock 284hp and 306ft lbs, the guy told me right up front not to expect high numbers from his dyno and stated it would be 10-15% lower then the dyno I have been using, now with cams and heads it only made 301hp and 290 ft lbs, kinda broke me down only gaining 17hp and lossing torque.. I talked with the owner and he said bone stock 05-09's with autos make 240hp on his dyno and 5speed cars make 250hp so if you figure a 2010 should be 260-265hp then I picked up 35-40 over stock, I know the stock intake and exh is holding me back, I'm ordering a JLT intake installing the extrude honed stock exh manifolds next, then back to the dyno, I was really expecting more hp then that, I might just pull the valve covers off and make sure the cams are timed correctly....
