Default Too much movement removing crank bolt. Advice?

Trying to remove the crank bolt, everytime I have ever done this before (not LSX motors) there was little to no movement in the crank. I have the parking brake set, car in 4th gear and when I attempt to break the crank bolt loose it seems like the crank will just keep turning (not freely it will stop but it doesn't feel "solidly" stopped) and I am hesitant to really apply any force to brake it loose yet. I don't think there is a problem the motor always runs fine, just want confirmation or warning as to how I should proceed.

Put it in 6th with the park brake set. If the clutch is good and doesn't slip it will hold it while you break it loose.

Do you still have all of your plugs in? I just did mine last week and I got ahead of myself and took all of the plugs out. The crank would just spin forever. Put 7 of them back in and broke torque no problem.

Put a pry bar against the block and pulley.

Your park brake must not be holding. Mine felt rubbery but with an 18 inch breaker and 3 feet of pipe, the bolt snapped loose with a puff of dust. I can't see any way the crank would keep turning without the wheels turning unless you're not actually in gear.

I would think 1st would have the most hold on the flywheel/crank? i know when i broke my E brake i had to park in first because 2nd - 6th would not hold the car at all.

Install a 4.10 gearset. Really R would be the best right?

To back up that arguement: http://www.5speedtransmissions.com/6_speed.html

I was able to break it loose with a prybar and pnumatic impact.

Ya, the highest gear will hold the car the best.
