My front spoiler is missing, and mine runs around that 220 or under mark. Never over, just around right on the money. Never had an overheating problem with it. Ran 3 straight days of 1300 mile driving and stopping up/down Route 66 last year without issue. I do have a new radiator however. Still no heat issues. With the motor that is. Inside the cockpit, that's a whole other story.

When in doubt, flush the system. Chances are that if you just got it, it hasn't been done in years. Easy afternoon project that is not expensive or difficult & its not going to hurt anything to have some fresh fluids.

I'm thinking 220 is to high. Confirm temp using an IR Gun first. Then troubleshoot from there...

I have a Dewitts aluminum radiator, Stewart Stage 2 aluminum water pump, a 180 degree Robertshaw high performance thermostat, the front 79 rubber air dam, and the lower radiator hose with the correct spring on my 78 L-82 4 speed and it will run 180 on the highway and about 160 around town all day with no pollution control at all and 2.5 inch true duals with shorty headers. It used to run 220 on the highway with the stock cooling system (brass radiator and stock type water pump, everything else the same) and 190 around town on a 90 degree day. The 75-80 L-82's all run hot (220 + is normal on the highway and cooler around town, opposite what you would think). The L-48's from this era run much cooler probably since they do not make as much horsepower, have a much milder cam and a lower compression ratio which the smog heads are better at cooling. The motor is stock with 64,000 miles except roller rockers. Hope that this helps!
