Lifting a Big Block!

I have a 90 GMC and how mush air pressure should it take to life the front end with a 396 big block and a 700r4 tranny behind it?

90-100 psi should be all it needs so long as you are running 2600lb bags (and have trimmed out the front to suit). It doesnt make much of a difference bettween a small block and big block as to air pressure strangly enough!
