January, 2021 Update

I have been working on building this car on and off (mostly off) for the last 10 years. Will hopefully be on the road and shaking down issues this spring. I still have my black Kelmark car, but would like to eventually sell it once this V6 car is finished.

The last thing I have done recently was to install a pair of G Body mirrors, painted flat black at the moment. I will keep logging miles, and once I am confident in what is going on for cooling and fender clearances, I will jump onto the body work and paint segment.

Engine Cooling
I want to share my front radiator setup with the group. You will first notice I didn’t cut any visible openings in the front. You have up get down on the ground to see the openings. The front 69 Camaro spoiler forces air into the radiator when the car is moving. With my engine and radiator I don’t have temps over 200 degrees in all conditions. The car usually runs around 190. The fans only run if the car is not moving, which is preferred. My car is a supercharged V6 so maybe cools easier than the old small blocks. Any LS application should stay cool with this setup. I have about 3000 miles on it so far, including auto crossing, heavy traffic, and highway cruising.
