    Talking Lingenfelter 427 CID LS7 640 Horsepower Normally Aspirated

    Here is a recently completed 2002 C5 Corvette convertible with a Lingenfelter LS7 blueprinted engine assembly complete with the Lingenfelter GT21 camshaft, CNC ported LS7 cylinder heads, 4340 Kellogg forged steel crankshaft, Oliver 4340 billet steel connecting rods, JE pistons and more.

    The LS7 engine is putting out 539 rear wheel horsepower on 93 octane fuel and this C5 is sporting a set of Forgeline wheels, Michelin tires & and has the customer installed Lingenfelter mini tub kit to allow the giant 345 series rear tires on 19x12 inch wheels. The great sound comes from a set of American Racing headers and Corsa Performance 304 stainless steel cat back exhaust system.

    Music to my ears....sounds as good as it looks!

    Is this car an automatic or 6 speed? I'm courious as to how the GT21 cam is to drive?
