Pulled the differential from the rear axle and had a limited slip carrier or "positraction" unit installed with new bearings and a pinion seal. Stripped the rust and paint from the rear axle housing and finished welding on the spring and shock brackets.
Installed the front axle and suspension, along with the disc brakes. Installed the rebuild engine in the frame with the old transmission core. Waiting till the car is closer to complete to rebuild the transmission.
Made brackets and mounted sedan body on the large rotisserie to start working the underside. Cleaning off the rust, scale and loose paint. Will re-paint and undercoat.
A modern rear axle is bigger and needs a larger "bump" in the floor under the rear seat. A previous owner started this modification with a torch, cutting and leaving a ragged opening in the rear floor section. Using an abrasive disk we trimmed that opening into a rectangle, made sheetmetal filler pieces and welded them into the floor under the rear seat for axle clearance.
Our early 1970's 400 cubic inch Small Block Chevy is a great torque engine (6.6 liters baby), but I wanted the nostalgic look of a mid 1960's 327 engine. So we traded some parts to a friend for a pair of crusty old 1965 cylinder heads. They're known a "double hump" or "camel back" heads because of the casting mark on each end, which resembles the humps of a double hump camel. They were the best cast iron cylinder heads in the Chevrolet high compression small block line-up (302 - 327 - 350) in the sixties. They're old school and after bead blasting, machining and replacing all the parts they're good as new.
Also, we're using an old Edelbrock four barrel intake manifold with a front oil fill tube and a Holley carburetor. Danny bead blasted the vintage Corvette finned aluminum valve covers to help give it the look. After a little garage rebuild and paint it's looking rather retro.
