Cooling issues on my 46 Studebaker

My dad and are building a 46 Studebaker M-5, and we’ve put in a new crate 350. With a 3 core radiator. I was wondering if it’s normal for it to run hot. It’s around 200. We have a 16” 2500cfm fan pushing and a mechanical flex fan with shroud pulling. Any ideas or tips are welcomed. This is our second build. Thanks guys.

Best I have found down through the years is a crank-driven 18 inch, 7 blade suction fan only, pulling through the radiator with a thermostatic clutch and surrounded by a shroud with 1 inch of clearance all around the fan blade. The fan blade should be halfway in and halfway out of the shroud as you look at the fan blade from the side. The pusher fan is likely making a problem for the entire system.

Thank you I’ll try it without electric fan and see. I’ve heard that new crate motors run a little hotter to start with anyway. It’s not overheating just running hotter than we are used to

Retarded timing makes heat too.
What’s your timing like?

I will check it. I know it’s a little off for sure. We have not done any tuning other than just getting it running

200 these days is pretty normal, the 350's since 1987 came with a 190 thermostat and typically display 200 to 205 in normal use.
