i'm sure this has been asked before, but, i was wondering if there are any differences other then the super charger, between the lightning and other f150 5.4 engines.

 

SVT engineers added a forged steel crankshaft from the German Krupp Gerlach Company, sinter-forged alloy connecting rods, and forged pistons to lower the compression ratio to 8.4:1.

 

Everything is the same except the pistons. Same block, crank, rods, heads, cams, ect. Pistons are lower compression in the Lightning motor for the supercharger. This is comparing 99-up motors. 97-98 Triton truck engines were not the same.

 

thanks for the quick replies guy's.
