Project is going no where, that's my report
I have to clean the lower control arms and transmission crossmember and it's too damn cold of late and I'll pass. Waiting on 10" locking casters for make-shift axles, so I can roll the frame to clean and then it's off for powdercoat.
I managed to peak into the heads for casting numbers. I knew they were replaced with the rebuild. They're matching high performance heads, apparently installed on Camaro and Corvette 396/427 BBC. Word is 10:1 compression instead of 8.5:1 with the original heads. Couldn't tell you why.
For what it's worth, date code translation. I looked this info. up once already, but lost it. Think I'll save it this time
