whats the best way to open a old case? I think i have all the nuts ad bolts off, but it is still together very well. How should i go about takeing it appart?
do i have to remove the flywheel to get the motor apart?

It will be easier with the flywheel off. It will take a LOT of muscle to get the gland nut off. A Torque Miester will make it a piece of cake. CIP has them on sale for $49.
Do not forget the oil strainer plate, and do not pry into the split with anything. I used a reverseing quick clamp in the oil pump hole. Worked slick.

first, double check that *all* nuts and bolts are out...there is a 13mm or two nuts that are located at the forward(flywheel end) part of the number one cylinder area...they are normally covered in crud and therefore basically invisible...next make sure you remember to remove the sump plate and screen assembly....also the oil pump must be removed...then you can usually "pull" the halves apart but if the engine has never been apart or has been together along time it needs some "assistance"...there are a couple "tabs" cast into the case that you can pry lightly on and not worry about scaring the sealing surface....a deadblow hammer(or rubber mallet) can be used lightly on the large (six) case studs to help break loose crud or old sealer....goodluck

I always take the flywheel off. I figure it needs to come off anyway, and it's a lot easier. I did the Muir thing with a piece of angle iron to bolt to the flywheel to remove the gland nut. It's always worked for me. If you don't have a big breaker bar/cheater, you should be able to get someone with an air wrench to take it off. It makes it easier to separate the case halves with the FW off. I usually find a block of wood and hammer, tapping first at the oilpump end then the flywheel end, back and forth on the little tabs or parts that don't conincide on the mating surfaces. Also I use the area in the case behind the flywheel, so it's good to have it off.
