Mild Performance Work
I was thinking about doing some mild head porting and bowl blend along with a 7 angle Serdi Valve Job with the same cutters I use on CUP heads. If it looks good, I will probably re-grind the camshafts to a lobe similar to the ones I run in my "Outlaw" 604 GM Crate Engines.
They are pretty mild and drivable and make close to 500HP on a 350 V-8 normal headed engine, I would expect those lobes to make close to 300hp on a 2.7 with the added airflow from heads.
The same lobes run on one of the Modular Fords made close to 600HP so they really let the engine breath a lot better.
I think with all the emissions requirements they really limit the intake charge a lot and go for mileage as the family Intrepid has been getting 26-28mpgs since 2003.
