    Over-torqued Flywheel Bolt

    Hi everyone, I was changing the flywheel on a 5.7 truck engine that I am converting into a marine engine and when I was torquing the flywheel bolts, my torque wrench did not "click" at the 75ft lbs torque setting for the #2 flywheel bolt. The bolt now free-spins in that bolt hole. Not good...

    Fuel Pump Question

    Hi everyone, I'm in the process of converting a 5.7 SBC for a marine application. The long block that I purchased did not have a fuel pump, so I ordered a new one which looks like photo #1.

    What Distributor For 5.7L Non-Vortec?

    Hi everyone, I'm looking for a distributor to suit a 5.7L non-Vortec SBC with a 4 BBL Quadrajet carburetor, JEGS intake and mechanical fuel pump. After reading online, the "Thunderbolt" distributors seems very popular but as far as I know, my previous non-Vortec 5.0 didn't use that type of...
