Notch on the bearing(s)/carrier(s) towards the manifolds.

You also need to fit each bearing carrier to its original rod. Period.

and the cap has to be the correct way round with the correct rod too, there snapped so usually have a pattern that fits perfectly together.

your asking if both notches to the back not to the front yet your saying you marked everything as it came out?..:scratch:

have all the liners been hones with new rings?,that make it pretty resistant,cant you turn it a couple resolutions at all?

yes i am asking, this is my first time doing a bottom end,

i've been meticulous in disassembling of it just doubting myself thats all and i'd rather ask to be sure than bull through it and mess it up,

sorry i had them all loose and the cap of no2 and it moved tightly but it moved.

so i dosconnected all of the pistong and tigheted the main caps and no movement.

i have another block i tried the crank alone in it and fully torqued down bearing in the same places and it spins freely.

i'm probably making a balls of explaining it and making myself look like a ****

so with all pistons/rods disconnected and the crank tightened its still tight? in which case loosen one main bearing cap at a time then turn it, if it stays tight, then tighten it and move to the next cap untill u find the tight bearing, then take a look why.

i was going to use a fresher block as mine had been welded at some point so i might just re use my original block.

is there a difference between a block from 88 and 91?

If you have a fresh block lying around then why not use that one rather than the welded one? The blocks will be the same.
Careful with the liner seals if you swap the liners to new block!
