Bolt-on 437 Rear Wheel Horsepower to your LS1with this Performance-Proven Recipe
Mike Esterly of Lisbon Ohio is a PPG automotive sales representative by day and avid automotive enthusiast by night. When it came to choosing the right cylinder heads for his 2001 LS1 powered Corvette, Mike chose the Edelbrock/Lingenfelter LS1 CNC heads, #61969. Mike was so impressed with his off-the-shelf recipe for big LS1 power that he wanted to share his results with us. This is a real customer with real results using off-the-shelf parts.

With enough power to rocket this Vette to a mid eleven second quarter-mile pass while maintaining the drivability to accommodate weekend cruising at 28-32 MPG, Mike's results prove the Edelbrock/Lingenfelter LS1 Heads bolt-on and perform to the extreme. Mike has also shared that these numbers were achieved with a rather rich 11.8:1 air/fuel ratio; we're looking forward to Mike's follow-up once the air/fuel ratio is dialed-in.
