Review on 🔥 Spectra HVAC 94501 Heater Core by Tanner Miller

Ordered this radiator for a 1978 Chevy. Tubes, height, width, everything seems to be the right size. The upper tanks, where the tube enters the core, were slightly wider than the factory tanks, so the clamp holding the core did not fit. I had to move it back about 1/4 inch or so. Otherwise it is similar to any other heater core. It's aluminum and factory brass/copper. Aluminum cores transfer heat much more efficiently given the surface area of the fins, so we'll see if the heat is better or worse in winter. in, fill up, run. Not bad compared to the Geo Prism which took me 3 days to rip apart the dashboard.
