LS7 makes 730 HP on pump gas

[scottj]

For 8 years I've had a very fast track Cobra that has always had one version or another of a 430cid, full race, drysumped small block. Lately, I've been wanting to get more use out of the car, but that's hard to do with valvesprings that are only good for 500 miles. Also, I have no desire to lose power to gain streetability or compromise handling (big block) to retain power. Well... having followed the LS7 development program at Schwartz Performance over the last 27 motors, I finally had to pull the trigger and get one. Representing the high end of Schwartz's naturally aspirated street engine line is the 730 HP version running pump gas, idling smoothly at 920 rpm, while using a stock GM throttle body and the drive-by-wire pedal. The heart of all Schwartz's packages is the proprietary custom hydraulic roller cam that emphasizes drivability and good street manners... and it only weighs 380 lbs.

Now all I have to do is wait for this latest 14" of snow fall to melt...
