I would like to use a Ford racing short water pump for more clearance. What has the group used for pulleys?
I emailed Pete Mantell and he is looking for a price from his machine shop to fab some. I think the only problem will be finding a short (not deep dish) water pump pulley. The crank pulley can always be shimmed and alternators are easy to align.
Any suggestions from the group?
Thanks,
JB
Hi John,
I'm using the Vintage Air Front Runner set up, but before I decided to go with that, I got a set of brackets & pulleys from a 302 T-Bird. (I actually still have the brackets, pulleys & timing cover. If you're interested in them, let me know & I'll shoot you some pics.)

John,
Assuming you are going to use a "V"-belt drive in lieu of serpentine with the E351S Ford pump, pulleys are available at your local junk yard from 70's and 80's pickups, t-birds, etc . If your engine is a late model (4-bolt crank) 302, the crank pulley is 4-bolt (2-3/8" pilot) and the belt centreline is about 1"ahead of the harmonic balancer mounting surface. If you can't find a single sheave pulley get a 2 groove crank pulley and then the larger sheave can be lathed off - this will leave a 6-3/4" dia crank pulley – ( it was designed to run a ½" belt and if you use a 7/16" belt, the effective diameter is really about 6-1/4. The water pump pulley has a 1" belt centreline offset to the rear and effectively lines up with the crank pulley. - it is about 5-7/8" diameter.
If this is your direction I can try to post a pic of a couple of pulleys.
Graham,
I like your approach.I have a later model 4 bolt crank. Would you please post the pictures?
Thanks,
JB
John,
Hope these help? First shot shows crank pulley and WP pulley relationship. Second shot is of a 2-groove Ford pulley prior to removing the larger dia sheave.

I'll throw in an additional pic of the WP pulley - if I remember correctly, the E351S pump has a larger pilot so reaming/drilling of the pulley pilot may be required - not a big deal!

Thanks Graham!
The pics will really help. When I finish I will post my results.
