nope crank was perfect along with everything else, all std bearings. the next one will be when i get paid, bearings and gaskets arnt cheap
if it was checked and it didnt require any linishing/machining and the use of oversize bearings then youre right the info youve give here is sound and will work.
the if the crank needed linishing/grinding and therefore needed oversize bearings, then matty is right you need to check the clearance to make sure theyre right.

maybe its just me, but for the extra 20 min it takes to check the bearing clearances with plastigauge, its worth it just in case one of the bearings isnt right or the knob that checked the crank fucked up........20 minutes while putting it together is way better than putting the whole motor in just to get it running and find out one of the bearings isnt right, and then to have to pull it apart again........
Probably should check crank end float as well

agreed........
i have nfi how to do that, so why dont you go ahead and write an article...
Jason,
You need a dial guage to check end float. simply fit a known thrust washer , bolt crank in like you said.
Mount a dial guage on the front of the engine block with the measuring bit of the guage touching the front end of the crank where the balencer bolt screws in to.
Push the crank towards the flywheel end of the engine.
Zero the dial guage.
Push the crank towards the front of the block.
The distance measured on the dial guage is the thrust movement. If its within specs great, if not add or subtract the error from the installed thrust washer thickness and then get one with the correct dimention.

finish this build already!!
hmmm i forgot to do one on installing rings and valves.
i got 1 more ring to put int (broke and oil ring) and one more valve (lost a retainer) so ill take pics and ill get some build pics, shouldn;t be to long
a good simple article, but..............
spreading oil all over the mating surfaces of the main caps is not a good idea. it does not take much oil down the thread hole to get a hydraulic lock. then the block cracks or the torque is wrong.
All you need is a smear of oil on the threads of the main cap bolts.
