My dealer service Mgr.maintained that he could give me about 90 HP if I changed to a littlemore aggressive cams, change out the valve body and fuel processor, andport and polish the heads. I couldn't spend the coin at the time so I don't know, but he runs two race teams and he has a good reputation in the area.

 

The old addage applies her. There's no replacement for displacement. If you are getting into the cam chest it just makes sense to work the heads over and bore the jugs. You will be much happier in the end. You can get a real nice 95" budget build to make real close to 100/100 for around $1200-$1500 for the parts. If you have the time you can saqve tons of money doing the installation yourself.
