What Fan/clutch/spacer combination should be used on a 1970 Road Runner?

[bwayco]

Hi All,
What fan, clutch and spacer should I be looking for on my non AC 1970 Road Runner with a 440 6bbl, manual trans and 22" radiator (2998954) and shroud (2998328)?
Thanks for any help!

I’ve never seen a spacer used in conjunction with a fan clutch.

I have a few clutch fans that will work, and I’m out in Pinckney. I also have a 70 6bbl manual car, if you’re interested in coming out, I can hook you up.

Is the car and original V code engine? Didn't all 6 bbl cars use a 26" radiator? The 6 bbl max cooling A34 Super track pack cars used a 26" radiator # 2998956, with TORQUE DRIVE fan clutch, 7 blade fan, shroud......WITHOUT ANY clutch spacer. I believe that the Super Bird's used a solid drive, 7 blade steel fan an shroud???? Just my opinion.....

I’ve never seen a spacer used in conjunction with a fan clutch.

I probably need to explain further.
My set up is a bit unusual.
I currently have a 4 blade mechanical fan without a clutch and a 1.25" spacer and want to convert to a 7 blade fan and clutch to help with cooling, but don't know if I need a spacer or not. The car was originally a 383, manual trans and 22" radiator and I changed to the 440+6 and kept the 4 blade fan and cooling was not too much of an issue. I want to "upgrade", but don't know what parts will be the best fit.
I am not quite sure if the combination of fan (2863216) and clutch (2806070) will fit into the OEM shroud, which is 20.75" in diameter.

Test fit, take some measurements and call bouchillon. They sell aftermarket and OE pulleys.

I had to use the (I think) short Jaguar fan clutch (2765) in my 1970 Roadrunner with a 22" radiator and 2863216 fan. The 22" radiator is more than 3/4" closer to the engine than the 26" radiator in my 1968 Coronet. In my Coronet, I used the standard thermal clutch (2747) with a 2863216 fan. In the last 2 pics, you can see the difference in the shaft lengths on the 2 clutches (no spacers are used with clutch fans). Can't help you with the shroud though, I haven't fit either of my cars with one yet.

WHY NO SHROUD? The third pix shows the shroud mounting tab. Once again, the Hayden clutch prevails vs the Mopar TORQUE DRIVE clutch # 2806070 .....is it's cost the consideration? Why not bite the bullet and do the job correctly by installing the correct core support and the # 2998956 26" radiator with shroud and the correct fan clutch......????....

I'm still working on the cars. I haven't even fired up the Roadrunner's 383 yet, and I'm probably gonna swap cams in the Coronet. I have the old 22" radiator installed in the Roadrunner for break in and to catch any rust/crap from the engine. Then I will swap in a new radiator. I have shrouds for both cars.

When I bought my road runner in 1977, it didn't have a shroud on the 22" radiator. Cooling wasn't an issue with either the 383 or later 440.
