Rock Solid Shifts – A Generation III General Motors V-8, build by Wheel to Wheel Powertrain, reached a 6.86 second quarter mile pass at 205 mph, a new benchmark for the community of GM V-8s to beat. This is quite an accomplishment, but how long will this record last? Probably not very long. That isn’t the point though. The Gen III’s V-8s have been a hit ever since they came out first in the Corvette, Camaro and Trans Am. This “new and redesigned” engine was simply a tweeking of the old, but ever so popular, small-block Chevy motors. It features lightweight aluminum block and heads, drastically improved airflow, modernized and more efficient electronics and ignition system, but still maintains (here is the clincher) the old push rod design.
GM did this while virtually every other car manufacturer on the planet was switching to more complex and revolutionary over head cams and/or multiple valves per cylinder style engines. however, this was one of the main factors that led to the massive amount of people that were drawn to the engine. It could be modded easily utilizing existing knowledge from the prior push rod motors. A simple few hundred dollar cam swap achieved astounding gains relative to cost. Some have reported over 100hp gains from the 5.7L.
While the first LS1 engine was a hit from the beginning, the subsequent versions like the LS3, LS6, LS9 and others sport even higher displacements and performance attracting more and more enthusiasts. Kurt Urban from Wheel to Wheel build his record breaker with a 6.0L block and a twin turbo plus nitrous setup boosting more that 30psi.(1,900hp)

This was only because of a weight requirement. The LS7 7.0L sports even more potential. I think we are going to see even more incredible accomplishments and awesome speed from these engines.
