68 RR 383 Still Getting Hot

[pnora]

Yes, they are both pulling. They are controlled from the Terminator EFI, #1 on 170 off 160, #2 on 175 off 165. Have them set there to get them going fairly quick, They are consistent. Thanks.

So they never shut off with the temperatures you are seeing.

No, they do not.

No, they do not.

What temperatures are you seeing on the radiator? Sample upper and lower tanks along with the core.

I have not done that yet, will do. Probably be a couple days, I'm committed through the weekend.

Just an idea for some data that might tell something. What block, heads and head gaskets are you using?

It's the original 383 block .040 over, stock 889 heads with machining and valve train work. I believe the engine builder used Mopar Prefomance head gaskets.
