do the 302 shortblocks have the same internals as the regular 302?

 

the difference between our Grand Marquis engines and truck and mustang motors is the cylinder heads restrict the flow along with the cam is different... the other stuff is the throttle body and EGR spacer... the upper intake is different than a HO also because the bore is larger on the performance engines... kinda stupid that Ford put the weakest 5.0L in this big of a car
