Wondering if someone can help. I have a 1997 Explorer complete Engine does anybody know the hp of these, I was told around 270? I want to build my motor to have 300 to 325 hp should I build my original 5.0 up or go with the Explorer. Either way staying with the GT40p heads is going to be on either motor. thanks

You can make that kind of FW power with the right cam and a very well thought out combo of parts............but not the stock or Explorer cam. You'll need as much compression as you can run too.
