Indeed, I was surprised to hear that number BUT... it is still 3,700 lbs!! It's a good start for sure. 200 lbs = two tenths off your ET. Did you weigh your bumpers before you took 'em off? Or the heads?

We've mentioned this before here but aluminum strut bars on the street are not the safest idea, especially since that heap is so nose heavy with the windy pachyderm. I considered them at one point myself but decided against it. Better to have some beef there, those things take pretty much all the braking force applied to the front end. The master cylinder is a no brainer though.

Perhaps now that you have the J bars tying the front together you can safely remove some of the inner fender sheet metal since it's not supporting anything anymore.
