The EFI myth

@Jarlaxle
I agree. Interesting to note I have a Street Demon 750 1904 with the polymer body.
I daily drive my Duster and I've had no issues when I was driving my duster here in Utah when we had 100-102+ degree weather. I live at 4500 ft altitude and my 360 has 10.2 compression.
Much like the thermoquads the polymer bodies does helps a ton with the fuel heat issue, the airgap intake helped a bit too.
I use a 195 thermostat, and she ran in the 205-215 which is fine (my wife's 12' Tahoe runs in the 210 range as well).
The only issue I had is when I sat in traffic barely going 5-10 mph in SLC for over 45 minutes and it was 103 degrees out. She started wheezin' a bit once the temps read 235+. Luckily once I got past the heavy traffic and got some airflow the temps got back down moderately quick. That issue I believe is mainly due to not having a fan shroud.
