I Have a 67 Cougar With a 351W (motor year 70’s) that currently has the stock V pulley set up. My Engine only has The Crankshaft, Water Pump, And Alternator pulleys. My Car does not have power steering or A/C. I would like to purchase a serpentine belt set of pulleys. Is there anything I need to know before I just go onto Summit and purchase some. I seen some kits from $200-$500+ . I’m not sure the difference in them beside the finishes so if any would could help me before I purchase that would be awesome! looking to spend around $200-$250 . thanks everyone !
Haven’t researched the aftermarket much on these. But I retrofitted a factory set-up from a Fox-T-Bird to my 351W. But I also have AC and Power Steering.
Beware, you might need a reverse rotation water pump depending on what direction the belt spins the pump. The stock set-up are reverse rotation.
Ok. Thanks for the response. My water pump rotates clockwise. Waiting to hear others advice. Thanks!
There aren’t many, if any, others on here who do mods like these. Most like to stay closer to stock. So I don’t know how many other responses you’re likely to receive. Good Luck regardless.
Thank you I appreciate it. You don’t ever have any problems with your belts jumping around?
I am running a serpentine belt from crank to alt. to water pump and also have a/c and p/s but they are being driven by a V belt to keep everything turning clockwise.
You can use your alt. adjustment to tighten the belt and there is no jumping around.
Here is an option https://www.cvfracing.com/ford-289-302-351w-serpentine-conversion-kit-alternator-only/
I have the v belt tight and just a little bit of jumping still. I was led to believe the serpentine belt set up was better than the old V Belt set up. Also I have a brand new motor and would like to put new polished pulleys to not only improve the looks, put hopefully improve performance.
Wow that’s a hella nice set up! I’m almost positive I have a clockwise water pump but i better double check before i purchase
No belt jumping whatsoever. The tensioner keeps everything tight no matter the RPM.
That is a good deal on this setup, and if you have a 70 351 with a V belt driving your alt and fan you have a C/W water pump.
Ya, that is less expensive than others and the quality looks great online. This will most likely be my next purchase! thanks for the help!
I did the kit from CVF Racing. It worked really well, but be aware you lose space between the engine and radiator.
You will have to deal with the pump to go to Serpentine, unless you want a crazy belt setup. You could always go with an expensive aftermarket setup like March, but if you want to do it cheaply, you could easily pull the stuff off a late 80s or 90’s era Ford truck.
I put an '89 5.0 HO setup from a Lincoln Sports Coupe into my Cougar, and originally kept the '67 V-belts. However, I had so much trouble with the high output alternator (which my EFI really needed) squealing, I decided to go serpentine, and it worked much better. Zero fuss.
There are tons of waterpumps available for these engines, some with inlets on the driver’s side, and some on the passenger side. I think you could probably find one with the proper rotation, depth for the pulleys, and with water outlet on the correct side for your radiator. If you just want to grab the pump off your donor engine, you’d probably want to buy a new one anyway, so take it to the parts store and match things up. Another way to get around the ‘wrong side’ problem of inlets and outlets is to have a radiator shop just move the connector on the radiator. The best cooling is usually achieved with the bottom hose on the driver side, because that makes water flow through the whole radiator instead of just down the passenger side.
Last but not least, they sell hoses that cross over underneath your crank pulley to get to the ‘other side’ if you’re desperate enough to do it that way. With radiator hose tendencies to collapse when they get hot, with the engine being revved, I’d be hesitant to suggest this setup.
