Earlier this year, we did a 706 truck pull engine, using a Dart 11.1 tall deck race block, with raised cam, iron, with billet caps. Shipping weight was over 330lbs!!. I called it the PB Nut Blaster block, as moving it around, you got an instant hernia, lol. For a drag car, No way, WAY to heavy. For the truck pull deal, just fine.
