96 four Winns with Ford 302 rebuild questions
 

Hi all,
I have a 96 Four Winns 190 Horizon with the fuel injected 302 Ford engine. Has a lot of hours and a knock so I'm going to rebuild it. I have several Mustangs so I'm pretty familiar with this engine. My main question is,this has the Ford speed density fuel injection set up and it is not a roller cam block. Can I either bump the cam a little bit with this computer set up or switch to a roller cam block without messing up the computer. Looking to get maybe another 50 hp out of it. Figured cleaning up the heads,roller rockers,and a very mild cam would wake it up a little bit. Does anyone have any experience with this situation? Thank you very much in advance for any and all help!

Thank you,
Jim
