I need help. My Continental has had a 460 V8 swapped in. For any others out there with the same swap, could you tell me what you did for a radiator and fan? Are you running AC? I am having issues with temperature creep on warm days, without AC. I've tried everything (checked tine up, new water pump, holes in T-stat, changed to big thick aluminum radiator and 2400cfm fan), but resolved that the motor may need to be shifted back to allow more room between the crank pully/water pump pully at the radiator. I only have like 3" inches and there is no electric fan small enough to put out enough CFM for a 460. The one I am using is the best I cold find at 2400cfm. I want to put the Mark VIII fan setup on it. Help

So I take it this car has a pusher fan installed in front of the radiator? I use a water pump mounted 16? fan along with a 16 in pusher fan on mine but my car still has the factory 368. I also did a thread on overheating last year you might want to check out. Do you have any pics of this engine and radiator in the car? Also, what kind of temp gauge are you using?

Today I just installed a new mechanical gauge with probe in the intake near the t-stat housing.

I have a Derale push/pull fan 2400cfm. I currently have it set up as pulling and mounted on engine side, because at some point, I want to mount the condenser and get the AC working. The outside temp was about 70 degrees. I drove the car and let it idle in the shop. The temp would go to about 185/190 on the gauge, 182 or so on my infrared heat tester, then the fan would come on, cool the car down, and shut off the fan, even just idling in the shop. I have a feeling I could go anywhere today, with no issue. The issue is when it is 90 degrees or more outside and I get stuck in stop and go traffic. With the old mechanical gauge, it would creep up to 215/220. Once I got moving it would come down. I think 2400 cfm fan may not be enough when idling at signal lights on hot days. I am running a Griffin Aluminum radiator, three inch core with (2) 1-1/4" rows. It has a sheet metal shroud for the fan. I am running a 180 degree T-stat, with some bypass holes drilled in it. New water pump.

I have the original 4-row brass radiator for the car, with original fan shroud, but no fan. I am considering trying to mock it up, make sure the 460 pump shaft/fan will align with the 368 fan shroud hole. If so, re-core the original radiator and try going with the steel fan. It just seems like at idle, the electric fan would be better than the steel pump mounted fan. I could also try a pusher fan, like your setup. But how would that work when I go to install the condenser someday? I could space the condense out to allow for a pusher between the condenser and radiator?

I'll look for your link on overheating.

As you are not trying for originality with a 460 do not try for the metal fan. 368's had no fan shroud so whatever you have is not the "original" fan shroud. I would mount a digital sender somewhere and check that as the stock gauge may not be calibrated to the sender in the 460 there is 12 years between the 2 engines and I know that I have hade a hard time finding a sender that is correct for the 368 so first things first see if it is reading correctly.

Also adding an overflow bottle with a cap that lets it pull back the overflow would be a good idea. You also may want to get a smaller Water Pump Pulley to increase the flow.

Hello could you have a exhaust leak into water jacket? There is kit to find out .

Hello could you post photo of 368 shroud. Is it for sale?

My guess is it is the one from whatever car donated the 460 (Mark III or a 1968-1978 Continental) and the radiator to match.

This should work. I used on on my 20KW Koehler stationary generator and eliminated the fan, altogether.

I appreciate all the help. Was hoping for some miracle advice from another car with the 460.

I am using a new mechanical gauge. My biggest issue is there is just not enough room from the radiator core to the crank pully and water pump pulley to get a really good high cfm fan. With 3" inches for the Derale 2400cfm fan, I have about 1/4" inch before hitting crank pulley. I may have to see if I can move the 460 back, but then the pan looks like it will hit the cross member. I don't know much about the 460, except it runs excellent, with good power and torque.
I don't think anything is wrong with it, just too big. I could go back to a 368, but I'd need everything.

Do you think I am better off with the cleaning/recoring if necessay the original 4 row brass radiator, verses the new Griffin aluminum? All else being equal? Playing with water pump speed is an interesting idea. But at the end of the day, I think I need more cfm moving through the core at idle.

Are your fans thermostatically controlled? That might be your problem. Too high of temperature passes and they come on too late. I run my car with a 160* thermostat. My fans are not thermostatically controlled just on when the ignition is on. Also, if traffic is completely stopped, say for an accident, I will shut my car off. I also will throw it in neutral when traffic stops and let it idle. So far so good, I’ve been in a few traffic jams and it never gets over 190. I also don’t have or run A/C.

Hello How about putting up a few photos , maybe we will see something
