Hey guy's i just picked one up ,got it off ebay great deal .but the pic's show them as silver block,mine is black ,is it newer off the line color of the blocks being sold now ?.Also took the back plate off to check for casting particals, one of the cleanest motors i've ever seen inside.Problem the connecting rod oil groove is facing the back off the block not the carberator side does it have a groove on both sides or should this be pulled apart?Sorry ryan6682 i should have checked your prices first
