    Re: 318 rebuild advice

    Are you building a drag boat engine? If not, stick to stock with the offset. Less piston slap and noise, especially when the motor is cold.

    ..."The wrist pin is not offset and thrust walls are symmetrical."

    And how did you determine that, by eye balling it!

    "You can lead a horse to water, but you can't make him drink."

    Do it your way and listen to the pistons knocking like crazy if one's a reverse rotator. (The pin offset's purpose is to prevent...

    Re: 318 rebuild advice

    I had the head off my starboard, reverse rotating 360 and I can assure you the pistons had a distinctive "F" on them--and they were all pointed at the distributor end of the motor (as they should...

    Re: 318 rebuild advice

    I STRONGLY recommend buying a rebuilt long block instead of a local rebuild. The prices for Mopar rebuilds can't be beat.

    I've done it both ways and, guess which way worked out best?

    Re: 318 rebuild advice

    IF the valve reliefs are only on one side of the piston, yes.

    Re: 318 rebuild advice

    There's either an " F " or a notch in the piston top that indicates installation direction. Putting them in the wrong way doubles piston slap damage--not good.

    Just to clarify: The "F" mark on the pistons should face the REAR on reverse rotation motors.

    Re: 318 rebuild advice

    If that's a reverse rotating engine (which I suspect it is) then tell your mechanic to put the pistons in with the "F" facing toward the back. If not, you'll have massive piston slap. I assume he...

    Re: 318 rebuild advice

    Reverse rotation on single screw boats is very common.

    If you want reliability, buy a rebuilt long block from a quality supplier (like Vesuvio). You can't beat the price and they are already...
