Is this a race only motor or street and strip? I have built several motors like that, both B and RB blocks. Does he want to use a Mopar 440 crank to make the stroker or a after market crankshaft? KB sells a forged piston for the low deck using a BB Chevy type after market rod, I don't remember how long though Thumperdart has one that runs pretty good, for a little motor
