Well, I thought I had my record book with me and realized I left it in Detroit. Here's what I can add or subtract based on my memory banks. Some items may not have any or much weight loss compared to their steel counterparts such as water pump and balancer belt pulleys. * Iron heads replaced with Indy SR Aluminum units. 49 Lbs loss. * Iron water pump housing and water pump replaced with Aluminum units. 11 Lbs loss. * Edelbrock Victor 440 Aluminum intake manifold saves about 20 Lbs. * Fuel pump removal all together gets rid of about 3 Lbs. * Aluminum brackets for Alternator gets rid of about 1 Lb. * Distributor hold down bracket is aluminum. Loss of only about 1/4- maybe 1/2 lb at most. * Headers will lose about 10-20 Lbs or so over iron manifolds and gain some horses. * Bolts, nuts, washers and screws holding up low stress and light components were almost all replaced with Titanium and or 2024 T aluminum. * Headers, water pump housing, water pump, timing cover, valve covers, intake manifold, Alternator, oil pan, oil pump, carburetor, Distributor, starter and motor plate are all held on with Grade T6 titanium bolts. $$$ doesn't make sense, but then again neither does this car. LOL. * Forgot the weight differences, but the fuel lines from the tank to the engine are aluminum. The lines by the carb are teflon super lightweight by Russell. Valve covers are super lightweight stamped anodized aluminum units with the MOROSO logos shaved off and finished and painted Chrysler 426 orange to look like regular factory steel covers. About 2 lbs or so removed with that alone. So at the end, perhaps 90 or so pounds removed. One item I have not done as of yet is an all aluminum oil pan by Steffs to replicate a stock deep sump Moroso pan. Just have not gotten to it like many other things.
