2005 Chevrolet Corvette C6 - Less is More

Doing a Lot With a Little: C6 Edition

Clichés exist for a reason and today’s feature will show you exactly why we’ve grown to live this phrase vicariously through LS technology. While there may be other reasonable ways to go fast for less coin (ahem…nitrous), this unbelievably reliable stock motor setup from the guys at Race Proven Motorsports got our drag racing senses tingling. The setup has stayed together for quite some time which you might not see with the other, more gaseous power adder.


To clear up any potential confusion, we will discriminate for you. "Stock motor" is industry slang meaning that the bottom end of the engine has remained untouched and no head work has taken place. Aside from upgraded valve springs and head studs, Mark Alfano’s 2005 C6 Corvette fits this description to a t. As a matter of fact, the only go-fast parts thrown at this monster are bolt-ons and a healthy custom cam from Race Proven Motorsports in addition to the smallest of blowers in the form of a V3 supercharger kit from A&A Superchargers. The forced induction setup is fueled by pump gas aided by an AIS meth kit.

Even with such little modification, Alfano is able to fire off 9-second pass after 9-second pass. With the help of a McLeod RXT clutch, 1.4 60-foots are common and we even see the occasional 1.3x 60-foot as we did on his personal best pass of 9.74 at over 145mph.


To even further debunk the notion that brief cases full of money need to be burnt in the name of going fast, the 707whp/628tq setup is backed up by a factory t-56. We will just go ahead and assume that the twin disc clutch may be a savior in this scenario.

While there has been little to no issue with the current setup, Mark is looking to undergo a few supporting modifications to back up what many believe is racing on borrowed time. The T-56 will soon be dropped in favor of a stage 6 TR6060 transmission from RPM Transmissions and a stage 3 C6 Z06 differential will replace the stock 2006 differential that is currently in the car. While no plan is in place for any future power modifications, it will be exciting to see just how far the limits of this stock bottom end LS2 can be pushed. Stay tuned!
