Thread: 1980 Corvette 350

Perry,

I would check the T-stat to see what the rating is. I had a 77 Vet that ran 215+ all of the time. I found that it had a 160 deg t-stat. I changed it to a 180 deg and it ran 180-185 all of the time.

The way it was explained to me is that the coolent needs to stay in the radiator long enough to cool it off a bit before going back to the motor. This was from a Corvette geru.

Not saying that is the answer for you, but it worked for me.

I wish I'd thought of that

I was looking more into fixing the over heating issue. I did not even want to comment on the 200MPH question.

It also allows time for the coolant to absorb the heat from the block/heads to be carried into the radiator. I am also a fan of the sleeve type of thermostat and not the cheapie poppet style. Most of the parts houses will gladly sell you a cheap poppet style for around 5 or 6 bucks. Ask for a sleeve type or get a "high performance" unit from Summit or Jegs. It usually costs a couple bucks more but the performance difference is well worth it! IMHO / FWIW / YMMV
