71 Dart 410 stroker ..

Well...it started off great today...I never had a crank turn so easy...wow..
i began knocking in the pistons on the odd side of the engine...everything goes great..turns over so smooth...
start on even bank...wow...it does not turn over so easy...and after two pistons...houston we got a problem...
I know the crank needs narrow rod bearing...and I thought that is what i ordered from Sealed Power 8-7125CH..but taking a second look at the bearing they appear not to be narrowed...ok...so have i have set of Clevite CB481HN coming from summit ...hopefully tomorrow..
