440 build for a tow rig/"muscle" truck?

Found another potential option for pistons, Speed Pro L-2266F... anyone have experience with these? Looks like they've been around for a while, used to be branded as TRWs if I understand correctly? Are they still heavy like the L-2355F? They sure look like it lol.

Got a lead on a BB 727 for $200, gonna go check it out tomorrow and if it looks good I'll bring it on home.
They are very heavy and will probably be about .075 below the deck. The ones I had were.
