Another point to keep in mind ... is we like to keep our vintage car engines less than the 195 degrees that the OEM considered appropriate.

This gets into some math, but the higher the thermostat...

Not sure if it was best practice or not, but I left mine in SPI epoxy. Mine won't see much rain ... so it may depend on how the car will be used/stored.

Yes I read that at the 7 day mark it should be at 70-80% of strength, so that gives me a target.

If the drum moves in and out on the studs even a tiny bit, but won't come off ... then it's the shoes that are hung up. Back off the adjuster as far as you can, and try again.

Still stuck, then...

For the DIY'er .. yeah, an electric setup just isn't ideal in our vintage cars without a huge investment. As for the HP, spend that electric fan money on some other goodie for the extra HP.

After some research it does appear that 4000 with fiber is considered at the least a replacement for wire mesh, and in some cases superior to metal reinforced ... really depends on application.

There will be rebar in the thresholds of the door openings, and in the lift pad. I don't think there will be any mesh at all. The original spec was 3000 psi concrete with mesh, the concrete "guy" is...

Hey, the Navy used those redneck AC systems for decades, probably still do. Pump 50 degree seawater through a heat exchanger and blow air through it.

Can you post a picture of the radiator/fan setup?

Hopefully you are not using one of those dual electric fan setups with the shroud about 1" deep. They only use about half the radiator.
