Its just a suggestion on something to consider.... if it annoys you as much as it seems to, I'll drop it.
I just don't see how it would take parking it for 5 minutes with the hood closed after 2 back to back runs and driving for 15+ minutes with all the air flowing through it to heat it back up to normal. The underhood temp on LT1's is too high for me to think thats causing it, but it might be the only thing making sense.
