I think 500 pounds should do it. If you can't come up with something that heavy I might be able to persuade my mother-out-law to come to your place and car sit for you.

My guess would be: 575lbs. for a complete sbc (power steering pump, smog, etc.), 525lbs. complete engine w/ aluminum heads, 420lbs. for a long block w/iron heads.

575 for a dressed all iron headed sbc give or take a little depending on the particular accesories used

According to the Specs I have - for example:
1966 L30 - 327 (dry wt. w/ clutch) 622lb
1978 L48 - 350 (dressed / dry) 622.4 lb
1978 L82 - 350 hi-perf (dressed/dry) 640.70 lb

so somewhere in the vicinity of 600#

thanks for all the input, i went ahead and made spring compressor using 9/16 b7 all thread cut about 17" long and had a buddy machine some 3.5" dia 1/2" spacers, then i cut some corded rubber to protect the paint on the lower control arm and frame. put some nuts on both and compressed the springs until the upper bumper wasnt touching the frame. thanks again

Be careful! That all-thread is not the same strength as the bolt in a real spring compressor. It probably has coarser threads, too.

It could break.

no worries b7 isnt grade 8 thats for sure, but 1125psi tensile or 23000 ftlbs i'm not worried. plus the springs are installed i'm only compressing them an inch or 2, just to take the load off the upper bumpers.
