I have rebuilt a 1997 7.4 liter MPI (not the mag) and upgraded it with the Crane 168731 cam , gold rockers, crane lifters, push rods etc. the main difference from stock being the cam. I have mefi burn software.

Has anybody done an upgrade to this engine with this cam and if so do you have a successful fuel tune?

Thank you

come on, I find it hard to believe that no one has any input.

I am thinking the guy's that have spent the time and money to figure this out would be glad to update your computer for a fee. Just my .02
