I don't know what difference that would make or if the difference only occurred with the two lifters I was using for comparison. Just something to check and consider.
I also recall that one company - forgot which since it was so long ago - had the same part number for both BB and SB lifters, but lately I've seen them listed with different part numbers. Don't know why.
West Point ROCKS!
As far as aftermarket roller lifters go,except for the tie bars,early small block lifters are IDENTICAL to Mark IV big block lifters.
