if you let it idle for 5 minutes before trying proper break in, theres a much higher chance you'll be rebuilding it again right away due to a wiped cam

Just so you know, there is no pressure lubrication to lube the cam and lifters. All they get is what's thrown off the crank and rods and some dripping off the bottom of the cylinders and maybe some "oil fog" from the air in the crankcase. When you are idling the motor, the crank isn't turning fast enough to provide enough oil to be splashed onto the cam and lifters.

Please read post #11 on this thread for a guideline to camshaft install and break-in.....

There plenty of other reasons but let's start with whether that is a situation or not for your set up.

I've been 180 out all three engine builds and in one crank you know it cause its exactly the same thing you got. God just goes to show my luck. When the odds are 50/50 you'd think one out of three. I'll bet you mark then flip that rotor 180 you'll be cookin

No, the Chevy isn't directional like the Ford.

To some extent at idle in the shop running a bit hot is typical. Assuming the timing is set with some advance, the radiator is topped off and closed to make some pressure, there's no vacuum leaks and the carb is dialed in it may prove to be helpful to run a household fan at the radiator to stir up more air across it than what the engine does.

Besides, isn't Houston having summer like temeratures today, low to mid 90's?

Most timing sets come with a little piece of paper in them that clues you into that little surprise.
