Sorry it took a while to get back. I was doing some construction while the ground was soft. Here is what I found.
White exterior: Color production numbers are well documented until 1962. Then, for 1962, they only show a couple colors with known numbers. White isn't one of them.
Red interior...
That housing is used on many small blocks but isn't the same as the 66 327/300 housing in the link above. It points up at a greater angle, but it would be close to the right angle for the 300 horse hose as mounted on the aluminum intake. I can't say for sure but it will be close. It should be...
66 300 horse thermostat housing
66 350 horse thermostat housing
There were two different thermostat housings used depending on the intake manifold; iron or aluminum. They point out at different angles. See above links. If your 350 horse intake has the 350 horse thermostat housing, then use the...
Welcome to the CAC
Chevrolet didn't retain build records for Corvettes back then. They do have the number of each option and a few of the colors that were produced but not combinations. Without the VIN or any original paperwork it is truly like looking for a needle in a haystack. It might be...
I can't make out anything that says hatch either. If you could find a way to enhance that image to bring out the printing that would be great. I'd like to know the option code since it was never listed as an RPO in 81. In 82 the hatch
wasn't listed as an option either. It only came as standard...
That 3782870 block was used across most models back then. It looks like you are headed in the right direction. If you find details on the COPO I would be interested in what it is.

Welcome to the Corvette Action Center.
The only RJ I can find is in the NCRS Lime Book. In this case it is a 1957 283 4 bbl in a 7000 series truck which doesn't match the rest of your information. It isn't uncommon for GM to re-use stamping codes in later years. Your 327 block casting number is...
If I remember right, Chevrolet says 45 degrees. I found where some say 40. Also found that some have driven them down to 30 degrees F in an emergency but used lower speeds and care.

1/8' is within tolerance and it would be hard to correct for that small amount. Do a visual inspection of the body mount cushions. I had one lower half by the rear wheel on my wife's 81 deteriorate when it was only about 10 years old. All of the rest looked new. Today, that one and all of the...
I suspect that you might be looking at the wrong end of the car. If the right front spring is lower, loaded, then the left rear will be higher. Since changing the load on the left rear spring bolt didn't affect the measurements any, I'd look to the front. Check for anything obvious first like...
