Thread: L67 vs LS1 stock

With a 3.4 it seems to be close to even for me. Ive only messed with 2 and i killed them off the line. Guess they need the driver mod

Stock L67's are pretty slow and weak at high speed pulls on the highway. GM badged all the w bodies with "supercharged" all over the place but the facts are its just a 240 hp motor stock. The Ls1 was 350 hp and the Ls2 400. I like the performance of my modded L67 but my son drives the car most of the time. He digs the supercharger whine but I prefer the rumble of a LS V8
