Hi fella and fell-ettes,
My 65 New Yorker is on the road, and seems to to be running pretty well. There is some random pinging, so I got some 93 octane non-ethanol gas in it, and added some octane booster. Still have random pinging.
SO, I bought one of those laser thermometer thingys from Harbor Fake Tools, and the thing is reading as follows: upper radiator hose 170F; intake manifold under the air cleaner 335F.
I performed the same test on my 67 Newport 383, and got 170 at the upper radiator hose, and around 200 on the intake manifold.
That 335F reading sure seems high to me, but at idle with that reading, there are no outward signs of overheating.
Thoughts?
