Can anyone tell me about this poly block? Lower LF Block (cast) - 2468230 RF Block @ deck (stamped) - A 318-12-11 Side 12-3-64 Interestingly this block has "standard freeze plugs with no signs of haveing the land in the block machined out. The 66 block that I hot tanked which spun the #2,3,4 mains had the shallow "disc" type freeze plugs. Is there any rhyme or reason to when they used the different freeze plug types?? Thanks!!
