cobra= small block
GMC= Vortec
Chrysler (Ex Dodge Charger, Plymouth Cuda) = Hemi
diferent companies have different types of engines. i perfer the Chevelle (Vortec) over the Charger (Hemi) Pontiac has recently released ram-air, basicly the ability to super/turbo charge your engine with out puting in a turbo/super charger.
My friend drew a picture of a mini and out fitted it like a Dodge Pro Stock dragster, hence the hemi thing, thus i came up with the frase Mini With a Hemi, witch is now writen on the side of his drawing.
