JL motor worked great for me. I'm a club racer and race every weekend. The pinch went out at 6 gallons. I ran this engine hard and never had a issue. Ray A pinched it last week and I just got done rebreakinging. The head has some scuffs but this motor Rips! I wasted big $$$$ on motors In the past and will put my JL at the top of the list. It's the Mustang of motors as I see it. For the price you will dono better.
