I broke out the digital bathroom scale and weighed some parts today and this is what I came up with:
200 long block with pan, oil pump, water pump, fuel pump and balancer = 209 lbs.
C6 head with carb, rockers, and exhaust manifold = 89 lbs
Can full of bolts, pushrods, other stuff = 11 lbs
Add a starter, flexplate, alternator, pulleys and stuff for another 30-35 lbs
Total weight of fully dressed 200 ~ 345 lbs plus oil and fluids, etc.
My hybrid will have:
Crossflow alloy Oz head with valves installed and valve cover = 41 lbs!
Can full of rockers, pushrods, bolts, and stuff = 14 lbs
Two CD175 Strombergs w/air cleaner = 6 lbs
Enough tubing to build an intake = 4 lbs
Add a starter, flexplate, alternator, pulleys and stuff for another 30-35 lbs
Total fully dressed Crossflow hybrid weight ~ 309 lbs plus oil and fluids etc. Less than half a fully dressed SBC with iron heads and 200 lbs lighter than a fully dressed 302.
