    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    why is the clamp ring still in place? take 3 of the 6 bolts you removed and install them in the threaded holes to jack the clamp ring off.

    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    if you are re-using your cam, you can re-use the lifters. just keep the lifters labeled. would also suggest you mic the cam bearings as they rarely need changing unless you are going to fire-clean the block if you are re-using a crank, a new crank is about the same cost as reconditioning your...

    Mercruiser 7.4MPI Compression after head gasket replacement

    run it, then re-check. a new motor is 150-155 psi. over that is suspect gauge or something in the cylinders like water or oil.

    Adding straight gas to mix

    no. do not do that. what has evaporated is the fuel in the carb, so your carb has a bit extra oil. just run it, let it smoke a bit and then the extra smoke goes away after a few minutes.

    1988 TRANSOM REMOVAL

    remove the engine then remove the Y-pipe and steering actuator then remove the transom shield and tilt/trim pump (no need to disconnect) take pics of everything and label everything. while you have the transom shield off, have the tilt cylinders rebuilt.
