I don't think so. Just better heads and intake. Not positive on the forge part but don't think so. Also 93 and maybe 92 used weaker pistons than a few years before that.

The lower end of teh Cobra is the same has the production mustang. The changes for the Cobra motor over the stock mustang motor where..GT40 heads, Cobra spec valve springs/ R.Rs, GT40 intake, 65mm TB, 24lb inj, underdrrive crank/water pump pullies, Cobra spec cam, Recalibrated EECM.

The stock lower end in the H.O. is stout.


Also keep in mind since it gets forgotten. '85-early '92 have Forged pistons, all have forged connecting rods and cast cranks. The lower ends can outlast the hp levels of the stock block but when building a motor with an aftermarket block one would at that point go with different internals and not use stock internals in a new aftermarket block ( since they are no doubt building a high hp motor).

Looks like just pistons and rods though. Crank is still gonna be the weakest link.
