I definitely respect the WS6. It is a very fast car, but the numbers below, saying an LS1 with cams and headwork pulling 490hp at the crank is a little much. The corvette by Specter Werkes/Sports inc. had a bump in displacement from 346ci-382ci, new pistons, rods, ported and polished heads, katech camshaft, and free-flowing exhaust and it put out 465bhp and 473lb/ft torque. Funny but it only turned a 13.0 @110mph with 345 tires on the back. Malletts 435 a 26CI increase, new crankshaft, connecting rods, high compression Wiseco pistons, ported heads, new valve springs, push rods, carbon fibre cat-back exhaust. The engine put out 435hp/450lb/ft torque, 1/4 mile 12.4 @116mph.

Now lets look at the M5. 13.2 @107-108 mph bone stock. The mods on the WS6 would put the car 1 length ahead, and a poor M5 driver could put the car another two car lengths back.

Hans, checkout This site http://www.morganmotorsports.com/

You will see on the front page 413 RWHP with stage II heads and cam, and some bolt on's.

490 cranks HP is about 416 at the wheels, I was a bit off but only by a few horses. He even has a dyno sheet you can look at.

There are a few people on www.ls1.com that have over 420 RWHP with different heads and cam setups. So it can be done and these cars will run high 11 second 1/4 mile times @117 - 120 MPH.

This is all done with the stock lower end. So, I don't think 490 crank HP is a bit much. I don't post anything I haven't verified myself.
