"I will learn from your mistakes" I heard that!! LOL Hopefully there will be no mistakes. I talked with a guy up around Denton that put an LS1 in his 97 SWB and the reason the custom bend S&P headers wouldn't fit was because the eccentrics for alignment were facing straight up. He did use 5/8" adapter plates to raise the engine up a little higher for header clearance and then ground off the eccentric on the passenger side only. I'm going over to GForce today to talk with Jay on a 97 install he did. The only problem he has is the tach won't work. I asked if he had the tach calibrated for a 4 cylinder and he said yes so I"m not sure what his problem is. It's a show truck and the guy doesn't care anyways he said.
