I seriously doubt there is anything wrong with the engine based on running temps. It cools down very fast once it's moving, that proves its a low speed air flow problem.
As for the oil in the catch can, that definitely "could" indicate something is hurt (pistons) but.... If you are running Katech valve covers, no baffles and pulling ventilation off of the valve covers to the catch can, you will DEFINITELY push oil through the covers.... However a full catch can in a couple pulls is a LOT even with no baffles.
You have to tig weld some baffles in your Katechs. I literally NEVER get anything in my catch can, other then oily condensate.

Now, especially with normally aspirated cars, there's nothing to block the airflow and on the other hand, not that much hp/wasted energy either. With right timing, I've been able to get rid of running hot situation.
But on the other hand these experienced guys below have different opinion and I do respect them. So it's really up to you.
In any case, with your power level, I'd install an EGT sensor.
Comment: a bit more may be required.
How much advance "ajrothm" is running while cruising?
How about "Nino S"?

What's your compression ratio? And cam (roughly, no exact numbers needed)?
I'd say you're running too little advance.
But to be sure, either a dyno test or EGT temperature measurement would be needed.
Idle timing while stationary is now irrelevant. But those numbers are of course common.

So those appear to be the Spal Extream fans, not the brushless fans?
I thought you guys were building the setup with the Brushless Spal/Nuova fans? (Your advertisement mentions restricted flow improvement - hence brushless). I'm just curious as I thought about the non brushless Extream fans myself.

Finally getting hot here. 117f today, 118f tomorrow. Still ice cold AC and a smooth good running car. I love my Vette.

What kind of ECT's do you see in that heat?

Car looks great. Where did you get the good from? I'm interested in your results as I'm gonna grab a radiator and fan/fans depending on more data. Right now I'm on all stock stuff and on a hot day my temps are in the 198-203 range cruising and as high as 221 in traffic.

That should ease a little frustration.

I think I said start with a gtr r8 Gallard etc when we first talked. Putting $40k into a 100k works out better than 100k into a 40k car. D3 setup won't fit or work with cutdown radiator. So would have to deal with that.

I ordered a D3 setup this morning. Should be installed on the car by the end of the week.
