Going through new shipment of parts I got for my engine upgrade. All upgrade parts quoted are from Denis Welch.
Al head (with guides seats and valves, without rocker assy): 35.5 lbs
Stock iron head (same state as above) 84.9 lbs
Al flywheel 10.4 lbs
Stock flywheel: 28.2 lbs
Al backplate 7.7 lbs
Stock backplate 20.0 lbs
New starter: 9.5 lbs
Factory starter: 18.3 lbs
Alternator: 9.5 lbs
Generator: 21.4 lbs
Total weight savings: 100.2 lbs
This doesn’t include impact of tubular headers versus cast iron exhaust manifold, or triple Weber/manifolds versus twin SU’s (not sure which one weighs more).
Hopefully interesting info for others.
