FAQ:

Q: Which is better LS1 or LS6 intake manifolds?

A: First up was the LS6 intake. Designed as a factory upgrade for the LS1, the LS6 intake once again proved its reputation by significantly improving the power of our 6.0L. Compared to the LS1, the LS6 offered an additional 22 hp and 15 lb-ft of torque.

Q: How much horsepower does a 6.0L LS1 have?

A: Least powerful of all the factory offerings, the LS1 definitely limited the power output of our 6.0L test motor. Equipped with the factory LS1 intake and Accufab 78mm throttle-body, the 6.0L produced peak numbers of 535 hp and 468 lb-ft of torque.

Q: What makes the LS6 engine a good car?

A: The LS6 engine is a durable engine courtesy of its robust aluminum construction. It translates to few engine problems, most of which are manageable. The aluminum body is easy to maintain, as it is lightweight. The LS6’s key selling point is that it is powerful.

Q: When did the corvette LS6 engine come out?

A: The LS6 engine shares plenty of specifications with the LS1. It is like an upgrade of the LS1 as it is a higher performance compared to its predecessor. It came into the scene in 2001, featuring in the hood of the Corvette Z06. It came into the mainstream automotive engine market in 2002, and many car enthusiasts appreciated its power.
