GM Performance Parts LSX 454 - Is Everything Bigger In Texas?
|
The final test really validated how an aggressive cam and the porting of the PRC LS7 heads worked together to make tremendous power-a staggering 750.7 hp at 7,000 rpm with 624.8 lb-ft of torque registered at 5,600 rpm. Power increased by 32.5 hp at 6,400 rpm with torque posting modest gains of 3.7 lb-ft. At 5,200 rpm and above, the revised camshaft split that increases intake duration, and just as importantly pushes more exhaust, really paid off. LS7's are known for their marginal exhaust characteristics, and even in ported form the use of more duration on the exhaust pays dividends. For the power junkies searching for an engine that will idle and still make back-crushing torque and eye socket extending power, look no further. View Related Article
