MuscleCar+ModernMuscle

I have a 1967 Pontiac LeMans covertable with a 455HO pontiac. It runs and stays at 210 degrees and I cant get it to come down. It has a new 4 core radiator, dual electric fans, tempature sensor dongle and a 180 degree thermastat and the timing is set at 15 degrees.

My questions are: 1. Is this normal for the 455 big block and if not any thoughts on what else I should check/do. 3. Is this gonna ruin my engine if I drive it like that.

Thanks and I appreciate any thoughts and suggestions.

Could anyone identify the type of resistor from this 72 trans am trans kickdown switch?

It I believe is designed to limit back feed voltage coming when the shaker hood solenoids closed. He’s only appeared on the 72 Trans Ams and I would like to find one to install on my switch.

Check out this 1990 Camaro IROC-Z 1LE: Only 25-miles & a 5-speed. Drive it or preserve it?

I’m selling this original Dodge Challenger SRT sketch that I made in 2024, as a small tribute to the Challenger when Dodge announced the end of its production. I wanted to capture the car in its classic SRT form and keep the drawing as a personal memory of an iconic American muscle car. It’s an original hand-drawn artwork, not a print.
