150 PSI won't do you wrong.

it is FIFTY FOUR..not fifty TWO ..or 2 and 1/8 inches.
But ya,/\.this,if you can't get an air compressor.
You can always find a wooden SKID,somewhere.They are getting thrown out every day.
Strap the engine down to the Skid and get your fat friend Bubba( example) to sit on the engine like he is riding a Pony.
I used a 3 foot(or 42 inch,it was long) breaker bar and a 3/4 inch socket Marked 54mm(size).
Stop the flywheel from moving with a small piece of chain attached to one of the PP bolts and that stud in the top right rear of the keg.
Put the breaker close to the ground and JUMP on it...Bubba can hold it in place.
......
If the engine is In the car still,I had a Big Rig tire Mobile tire repair come over and blast it off with their impact!

I ended up just cutting the side of mine, so there's a good place to place a chizzle, and just used an electric jack hammer on that ****... open right up.. :D

and trust me.. all of you saying air impact blah blah blah.. this b***h didnt wanna come off.. and i also didnt have an air compressor good enough to power a 600ft/p impact, only thing i had was a 340 electric.

i just removed my fly wheel nut on a 12a i thought mine was stuck too. i soaked it in pb blaster for a few days spraying it before i went to bed at night. only reason days is because i didnt have the socket to remove it with yet. i used an ol electric impact from chicago electric. it took an unusually long amount of time to bust her loose . i used the impact then the ratchet then impact then ratchet. got tired of switching so i just used the impact for three or four solid minuets then it it came off. its not reversed threaded either. just a pain in the rear

I have a neighbor that fits in the bubba category 532 lbs hell of a nice guy ,big as a moose actually come to think of it he kinda looks like a moose maybe that's why everyone calls him moose .:scratch:

Probably not.

I've started using my propane torch to heat up the nut till shes red hot and use a 3/4" ratchet. doesn't take much torque.

I did it on 2 engines at the same exact time, 1979 fly wheel nut, electric Chicago impact also, didnt even spray pb, came right off.. 1985 engine, sprayed it with pb for 3 days, heated it up with a torch, tried to use a chizzle, mallet. Ended up having to use an electric jack hammer.

since were on the topic of flywheels here does anyone know of the proper torque spec for an aftermarket flywheel to the crank?? i have searched for a bit now and cant seem to find it.

i have an ACT clutch and pressure plate and i know the pressure plate to flywheel is about 25 ftb

thanks

Well, i know that the stock flywheel has to be torqued to 275-300 ftb :| which is really freaking annoying to get when you dont have a torque wrench strong enough... I had to wait for my nab that works at gm to bring back a torque wrench and i got it to 280.

Torque specs:
Clutch pressure plate to Flywheel: 13-20 ft-lb
Flywheel nut: 289-362ft-lb
