LT4 Chevy engine

Is it safe to assume that you are talking about an LT4 Chevy engine that is fuel injected? What year is it and also what body is it in? Also is it a converted LT1 to LT4 engine? Any mods done t it?

Temp

It all depends on the T-stat that you are running. if you run a 160 degree stat your constant temp should be aprox 170-180 degrees or if you have the factory spec T-stat of 195 degree you should be around 200-210 degrees. as long as your cooling system is functioning properly. As with everything this is just a base line temps can very up or down per car and situation. I hope this helps. I have a LT1 with the Lt4 hot cam with ported Lt1 heads and a few more tricks done to it. This engine is going into my 1931 Ford Model A Street rod. Also have a buddy that has a 1995 Camaro with a very healthy LT4 that runs very well at aprox 10"s in the 1/4. IMO I think the LT1-LT4 is a great engine, full of power and still gets good gas mileage.

Going down the road, the LT4 in the Corvette runs about 193, in traffic the 1st fan comes on at 230 and the 2nd fan at 250, its the same for the LT1 and the LS1 engines. hope this helps

If your engine runs 200*-210* with a 195* T-stat in a particular setup (car, radiator, fan, etc.), it will also run 200*-210* with a 160* T-stat. The T-stat does not determine running temperature, but the minimum temperature. Ed
