My boss was asking me about this on Friday and I didn't really know the answer... What does the (specifically) 97 Cobra 4v engine have for internals? Pistons, Rods, crank, etc.

Thanks

Well, I know the pistons are hyperutectic, and the crank is forged, not sure about the rods, but I'd guess they're forged also.

OK just watched it...wasnt as detailed as what i thought it was, but i got a tad bit of info:
built at the romeo plant
Crankshaft-steel induction hardened forged and fully counter weighted
cylinder block- aluminum alloy with iron cylinder liners
bearing cap- nodular iron
exhaust manifold-high silicon molybdenum iron
it never said anything about pistons

White97

Thanks for the info.

Yep, just need to confirm the pistons.

I'm 95% sure they're hyperutectic. I'd like to know what the rods are made of now, if they're not forged, why not?

Edit: According to Modified Mustangs, 4.6s have hyperutectic pistons and powdered rods, the only exception is the '03/04 Cobra, which has forged pistons due to the boost.
