454's with 250 blowers are basically 525SC's.... 525 horsepower, unless there is some other mods that up the HP that much. JMO....

Just reread and saw they were set up with dual carbs. Like you said probably 750's or so. They could probably be tuned for running without the SC's.
250's instead of the 525SC/177s will give a gain of 20 hp or so. Also a compression increase, roller cam, mild head work will be good for another 50-60hp. Done right, you can get about 600-625hp out of 250's on top of 454's.

Thanks everyone for the help.
I'm thinking at this point if it were too cost too much more for intakes and tuning to run without the SC's, I'd just keep on and pay more insurance.

Trust me. You will LOVE the blower whine and the sound of blower motors. Just take care of them and run good fuel.
