    When to chrome-moly endplate?

    At what Hp/Tq levels does haveing a chrome-moly endplate in a 555 become a need, because of the flexing risk? In an L-body.

    That has been debated for a long time. I've seen multiple engineers question the actual science behind it (as recently as yesterday). At the same time I know that most of them still run one because transmissions with it have tended to hold up better over time. IMO 300HP and up I would have one.

    I'm below 300hp, but I'm way heavier than an L-body. I've got one in.

    The stock steel plate is stamped and its not even supported in the middle. So it comes with a built in warp and said warp will only get worse with time.

    Cheap insurance in my opinion. The 555 isn't a weak trans, but they're getting pretty scarce. Anything to improve longevity is money well spent.

    considering the steel end plate gets worn thin around the holes the shafts pass through - any trans that has been pulled apart should get one regardless of power level

    Ok then! Well guess that's the next part to get purchased on the list then. Because my tranny has been a part and checked, looked awesome ( so I'm told, Thanks Reeves) power level will be over 300 at the FW now, and I like insurance! So...........Sold! Thanks for the info guys
