I have completed all the underbody modifications and assembly, as this will likely be the last On the Workbench post before finishing the body and putting it all together. The engine fit perfectly into the Revell 67 427 engine compartment. I added the surge tank from the AMT 63 and made up a master cylinder more representative of that used on the Z-06. The radiator bulkhead was modified to except the air intake and some additional plumbing was added. I had a chance to look underneath my buddies 65 Corvette and realized I had previously misidentified what was painted green zinc chromate. The two green pieces are seat securing nut plates. I also painted the spare tire carrier a more representative grey. Side exhausts are aluminum tube joined to sections of the styrene exhaust from the 427 kit.
