Yes you are right and i am wrong
I was thinking upside down LOL

Dead serious about the upside down engine shit though...
I was at the stage where i thought "Fuck it, its going in no matter what", so a turned it the right way up to carry on assembling it, and it rotated freely. I turned it upside down again, and it went stiff again (Just a stiff point once every full rotation IIRC) The oil pump was a brand new Burton Power high pressure jobbie...
