5.0 & 5.0 H.O

RE: 5.0 & 5.0 H.O
Well from what i've read the mustangs had a cam changine in '88 or '89. I want to say the reasoning I read was because of the fuel crisis? It was a pretty reliable source, but i've never checked specs on either so I don't know for sure.
So I didn't know if the cam was different in the mustang H.O. vs the mark vii H.O.
Also as mentioned above. The mustangs only had forged pistons in 87-92. They switched to hypereutectics in '93
I didn't know if the lincoln H.O.'s were cast, hyper, or forged.

and mustangs didn't just come with forged pistons from 87-92!! 85 and 86 came with forged in the h.o motors 85 being the first year replaceing the sand cast pistons used in 82-84 h.0 MOTORS 86 ARE NOT THE MOST desired due to no provisions for valve reliefs

I'm sure the Lincoln's followed the same pattern as the mustangs did with the pistons and cam designs. They put out the same ratings from what I have read.
In 89 the cam design did change a little when going to mass air.
This also changed the torque ratings from
285 ft-lb @ 3000 rpm to 300 ft-lb @ 3200 rpm
I.O./I.C./Lift 17°/69°/0.278 to 20°/76°/0.278
Duration - Int/Exh266°/266° to 276°/266°
Overlap 36° to 39°
