    Do you have any sound clips

    Asked by: Alex123
    We do not have any sound clips of this engine. There are a lot of options for induction and exhaust components that would affect the sound.

    Are these engines internally balanced or are the externally balanced?

    Asked by: Rich143
    This particular engine requires a non-weighted or internal balance balancer on the front of the engine but a weighted or external balance flywheel or flexplate on the back of the engine for a one piece rear main seal Chevy 350.

    Has the base Engine without the Intake and Carb already Dyno'd as well or is it only the fully dressed Engine?

    Asked by: HarleyTodd
    Yes, even though it is a base engine we will still add all parts that it needs to run on the dyno. We will verify the HP and TQ numbers, pull those additional parts back off and package the engine ready for a shipment to your door!
