Re: 55-56 374 Core Plugs

We have been supplying the 1 3/4 freeze out plugs in our engine kits as well as individually for nearly 40 years with no ill affects. On occasion we may have a customer that has issues but this in many cases is in part to heavy corrosion or pitting at the blocks surface area. In those cases when we are notified we work with the customer and supply them with a larger freeze out plug if need be to remedy the situation.
