    Long story short, I changed to a clutch fan on my 68 Road Runner (383) and now it starts to overheat if I idle around too much. I know I could try to get a fan shroud that fits and maybe a bigger radiator, etc. But I like the way it looks under the hood now and don’t want to change it.
    I just want to add a thermostatically controlled electric fan in ‘front’ of the radiator. That should more than take care of the heating problem and allow me to keep the stock looking engine bay (in back of the radiator support). But I noticed the radiator fins (in front) are in set back from the radiator core support about 2.5 inches. So I’m not sure which elect fan I can buy that can mount in front of the radiator and yet set back a couple inches to be closer to the radiator fins.

    Has anybody encountered this before and do you know if they make electric fans for ‘in set’ mounting to the front of the radiator? Which manufacture is best? As always, huge thanks for any help and advice. RRDon

    I want to keep this clean, uncluttered, basically stock look under the hood.

          kind of a contradiction wanting to keep it stock appearing and uncluttered , then wanting to add hideous looking electric fans, that would completely take the stock look out of it.
          a factory shroud is the only way to go

            Could the new clutch be faulty?

              So you changed to a clutch fan and now it overheats. That should tell you something. Did the fan diameter, number of blades or distance from the radiator change?

                I'm wit him^^^^ I will run a solid 7 blade anyday over a clutch fan and an electric fan to assist especially if you are trying to keep the stock look. I run a 7 blade no clutch on my decently modified 383 with a 22" rad and no shroud just like stock and it runs half temp on the gauge all day tops in the hot weather.

                  You do remember the premise of the movie Joe Dirt, right?

                  Ok, if you don't here it is. Joe got left at the Grand Canyon when he was a child and his parents never found him because they never looked where they last saw him.

                  Point? If your didn't overheat before you swapped the fan clutch, why not take another look at it. Maybe try a different brand? Did you go from a thermal to a viscous or vice versa? Between my Chevelle, Monte, and Buick, all are big block cars with working factory air conditioning, and they can all idle all day in the summer without getting hot. With all factory parts.

                  Hanging a fan on that beautiful B Body of yours would just look silly. Just one mans opinion.

                    My concern would be that adding a pusher fan in front of the radiator will obstruct air flow (to some extent) while driving, not to mention that, "keeping it clean, uncluttered, basically stock look under the hood" will do just the opposite in front of the radiator.

                    I had a similar problem on my '69 Road Runner, also a 383. A shroud solved the problem (with the factory direct drive 7 blade fan). The fan shroud is very small and not obtrusive at all AND very effective. Between the two, I think the fan shroud would be the better of the two choices and still keep your car closer to the original factory look you desire.

                      there's no mounting on the sides of the radiator for a shroud. I tried to find some but the kit I got doesn't work with this radiator. Frustrating. That's why I just want to put an elect fan in front and be done with it. ;)

                      My radiator does not have provisions on the side to mount a fan shroud. If you know of a fan shroud and a mounting kit to attach it that will fit on my radiator please let me know because I have not been able to find anything yet. I could buy a whole new radiator and order it with a fan shroud I guess but I really would like to do something simpler. RR Rad #s.jpg Thanks.

                      That's why I said I want to put the elect fan in FRONT of the radiator. Much less noticeable. The engine bay would remain as is.

                      Possibly, but it does seem to move plenty of air. However I can't tell for sure if it 'locks up' at the correct temp. It took forever to get it to fit right. Either way I just want to ram enough air through the front to solve the problem. ;)

                      Yes I know I changed the fan to a high performance lightweight 5 blade and added a clutch to reduce drag, and that NOW its running hot. OK, I understand that is the reason, but I still want to add a huge electric fan in FRONT of the radiator and hope that will fix the problem. If it doesn't work I'll rip the whole f**king thing out and start over. I already spent 3 years working on this car AFTER it was supposedly 'already' done. I was just hoping to find an easier fix for now so I can do the fall car shows. I don't take it to 'concourse judging' so if it's not 100 point stock config I could care less.
                      Thanks.

                      I wasn't trying to be rude about it, just in my opinion , popping the hood and seeing the electric fan right there in front would immediately take away from the stock look. I agree the clutch fan may be a problem with the 22" radiator. for comparison sake, I use a clutch fan , with a small block 2 core 26" radiator, a 180* thermostat and a shroud with my 440, and it never gets over 205* sitting still , in gear , for what seems like days in 95* weather. maybe you should look at the thermostat too, I always test them in boiling water before I put them in. I had 2 in a row that did not open right out of the box , and one that barely opened before I went and bought an expensive one that worked.
                      I just recently bought an aluminum 2 core 26" radiator because I like the look, and I don't even need the shroud and it doesn't exceed 200* no matter how hot it is outside or how long I run it.
