Red, Snapshot below taken from the 1955 2nd Series Chevy Truck Data PDF shows the dry weight of the 261 with clutch (assumes that's with flywheel, but doesn't say for sure if with bell housing) = 616 lbs. If you want a cushion on weight estimate, add 25 lbs for the bell housing and you should be close enough.
