Rod bearings arrived too. I purchased tri-metal standard bearings made by Taiho $38. Tried to buy the Clevite 77 P- series but they are no longer available anywhere in STD sizes for Rods.

Are the "P" series harder than the "A" series?

P-series are Tri-metal bearings. They have a steel backing, copper middle and aluminum surface. They are capable of handling a higher RPM than the A-series and are better on performance engines I’ve read. The A series are all aluminum.

    I think top layer in tri metal is lead or a lead alloy, not aluminium.

    Did you ever get the crankshaft end play worked out?

    Not yet, but I will before I move forward. I’ve been gone a lot for work lately. Dial Indicator on it way thanks to one of our favorite members CO who offered me one of his extras.

    He gave me one too.  Great friend!  So obvious isn't it?

    Haha!! Just trying to pay it forward.    :beer:

    What's the prospect of all three of us having our new shiny motors powering our cars at ZCON 2020?

    Maybe I’ll sneak in there too with a fresh motor - if I ever get the beast to stay together - lol

    You guys will be humming down the road and with my luck my engine will blow up 1/2 way there.
