Perhaps Ford has the same option? Just a thought...

Yeah Rich, I know what you are talking about. I think Chevy has a couple of different length water pumps too. I measured an unmolested 351W in a junk yard the other day and that water pump and mine are about the same length... about 6". I think the water pumps are the same. It appears the balancer is different. I think all 351Ws are 28oz balance... if so, I might be able to swap for a later model balancer. The one I have now is a Fluidampr ($200+ ). Maybe I can sell it on eBay or something. Anyway... I'm just wondering if the V-belt route is the best way to go if I'm gonna have to start changing parts. Maybe someone else can chime in on that one. The pic below is of the junk yard engine. (quite a nice engine... kinda wish I had the whole thing )

Definately going to go with a 3 core radiator. I think there'd be overheating problems otherwise. And as far as clearance goes I don't think there will be any problems even if I went with a mechanical fan. I think I had about 5"-6" inches between the end of the water pump shaft and the radiator. A shroud is a good idea too.
Dang Jim!!! make your own pulleys? You the man! Yeah, I'm definitely going to go with electric fans. Haven't researched radiators much yet, but I'm thinking 3 core will be necessary with my engine. Seems I've read that clearances are tight on some V8 swaps... would like to know now so I can prepare.

OK, some progress lately. On the pulley issue, did some research and found out that Fluidampr makes a crank pulley spacer... 5/8"... just what I need. Ordered one and should be here this week. This should solve my pulley alignment problems. In the pic below, I shimmed out the crank pulley with some washers to about 5/8” and all is looking pretty good.



Next, I’ve been thinking about those “hat” washers that fit into the body mounts. Everyone on this site either has them and they’ve rusted out or, like me, the PO did not install any when he replaced the original mounts. At $5.00 each and subject to disappear on me in the future (rust), I’ve decided to make my own. Got a piece of 1” stainless pipe and ripped it so I could compress the tube to about the same size as an original washer. Got some stainless flat washers and had a friend weld it up. This is the proto-type next to an original. Yeah, think I am over engineering this one, but what the heck… right?



And finally, been working on the slave cylinder mount. Cut out some cardboard templates then transferred it to 3/8” plywood. Mounted it up and… dang! I think this might actually work. Now to find someone who can re-create my plywood mounts in steel plate. I’ll let ya’ll know how that turns out.

Well done, Bobbo. I think your bushings are "up-town". I used EMT.

Bob the stainless tub mounting hardware ought to last you a while. I didn't go back and look, so I'll do it the easy way, where did you get the slave cylinder?

Jim, my Jeep originally came with the 151 cid "Iron Duke" engine with this slave cylinder. I always knew I wanted to try to make that work without having to cobble up a mechanical linkage. Would have liked to have gone with the hydraulic clutch bearing (not sure of the technical name for it), but those things seem to never get any good reviews. A shame though, it sure would simplify things alot.

More info Jim... looking at slave cylinders on eBay tonight and the same cylinder can be had for as low as $22 and free shipping (new unit with warranty!). I need a new boot for mine, but at that price, I might just get a new one all together.

If you need some steel plate cut out on a CNC machine, PM me and I'll give you the info on how I need you to send me what you need cut.

Thanks aggiejon... yesterday, got a piece of 3/8" steel and gave it to a friend who says he can cut it out with his plasma cutter. I told him if he can do that, I will drill the holes and clean up the edges. Thanks for the offer!

There hasn’t been a lot of progress lately that I can show. However, I have completed the clutch slave cylinder mount and I think it turned out great. Strong as h*!!… I think you could pick the engine up with that mount… don’t think I’ll have any trouble with the mount flexing. May have to work with the stroke a little when the time comes.



In more recent news, my body man now has his own shop (for now) and is slowly getting back to working on my tub. I have received new headers and will be test fitting them soon. (Got them from Advance Adapters) Starting to try to work out some power steering hose issues. I’ve ordered new hoses, but it doesn’t look like they will work directly with the Ford P/S pump. I’m probably going wait until I get the tub on to see how the hose routing needs to be before I make that connection permanent. I can’t get over how much stuff is on the drivers’ side of the engine… power steering hoses and pump, fuel pump, steering shaft, brakes, clutch… why can’t something be on the other side!
Once I get the headers mounted, I’m going to trailer the chassis to a muffler shop to see about getting the pipes run. I would like to try to keep true duals through-out… I’ll let everyone know how that works out.

Also forgot to mention that I'm still trying to cure my D300 leak. Figured out the leak (or at least part of the leak) was coming from the front output. Pulled the front yoke and seal... this is the yoke... notice the groves, I think this thing is wore out. (Like so much of the rest of the Jeep! ) I've just ordered a new yoke and seal. Since I'm having to change the yoke anyway, going with a u-bolt type yoke over the strap type.

Nice work on the bracket Bob. Yoke looks just rough enough to cause trouble.

The Rugged Ridge yokes I ordered did not have the correct dust shield, so you may want to hang on to the original. I had to drill a hole through the dust cover and dimple the yoke and spot weld them in place. Somewhere in my thread I have pictures of what I did.
