Title: 351W (427W) w/Canton oil pan ishiznitting steering rack
Post by: Cougar5.0 on September 09, 2017, 11:36:06 PM
Just wondering if anybody who's done a 351W swap has run into this issue and how they solved it. I thought the Canton was a stock pan with the "T" welded onto the rear sump area. I'm using the Chuck mounts that I bought years ago, finally they're being put into service :hick: Looks like I could shim it with maybe 1/8" thick washers?

You could do that, or maybe some offset steering rack bushings.

Car is already lowered, so I'm not too fond of lowering the rack. I read of someone putting rubber belting between the mount and k-frame to raise it up some, I need to see how much can be gained doing that. At least hood clearance doesn't appear to be an issue with greater than 1/2" there now.

Could you just space the engine mounts away from the frame to get some clearance? I don't see why it wouldn't work.
Is the 427 going to be NA or is the KB getting bolted to it?

No KB, this engine should make 600 flywheel N/A.
Yeah, somebody recommended using this stuff (http://"https://www.tractorsupply.com/tsc/product/baler-belting-2-ply-4-in-x-60-in") to shim up the mount, though I could just weld on some sheet metal as well.
Today was really annoying - I hadn't been able to bolt up the driver's side mount - turns out I had to grind away some material in the middle of the mount to clear a boss on the block. I got that done, then the ed lower part ishiznitting the steering rack - geez!
I'll have to separate the mount cuz I'm not unbolting the top part again! More grinding tomorrow.
I'm so tired and there's more possible issues just waiting for me to discover them.

So I used the Maximum Motorsports rack bushings and lowered my rack due to the Canton road racing 7 quart pan hitting the rack on the 351W my Bird and my car is in the weeds. You raise the motor and it might find the hood.

Interesting. I'd definitely need a bumpsteer kit. Funny, at the link you posted, it highly recommends against using offset bushings on the rack.:hick:
It seems that if I stick ~1/4" PVC pieces under the mounts, it clears the rack and I still end up with 1/2" above the elbow.
Unfortunately, I'm still dealing with the inaccuracies of these mounts - drilling out holes, twisting this and that, lifting and dropping the engine, yanking it this way and that. My ribs are ridiculously sore from hanging over the fender. I've wasted 6 hours fighting with these ed mounts, knowing that there's a dozen more issues I have to deal with before I can start the engine. :mad: Can't imagine anything I'd rather be doing to mutilate my 55+ year old body. :punchballs:

Should have used a Fox Mustang K member and mounts at this point....

From what I've read there is more clearance with the Mustang style mounts between the pan and rack when using a 351W block.
Although using a non stock pan could throw that out the window. When I had my Mark VII (it used fox Mustang style mounts) the engine sat a bit higher off the K member than my Thunderbird.

Maybe, though most of the advice I read on how to deal with the interference with the steering rack on a 351W swap was on the Corral. The comment was "hit or miss" as far as interference goes. I dunno. I think I'll be good once I shave the shims I made down a tad.

There's something else amiss. There are LOTS of Type 6 mounts out there in service.
Those lower U-brackets are the same dimensionally as the stock lower U-brackets. You have an older set of mounts (As they're zinc plated and not powdercoated), but those brackets could be the very EARLY style, which were a little shorter and only had one location for the main vertical through bolt. (At least that's what I remember. The last iteration had a siamesed hole to accommodate the Fox (86-88) and MN-12(89-92) differences.
If you have a set of your stock lower U-brackets, you can modify them. A 1/2" hole in between the two smaller bushing mount holes, and a welded-in reinforcement plate will suffice. That, or you can use a large OD washer under the head of the bolt from below.
I have extra of those large OD washers if you'd like some. You can use them as spacers under the bushings as well as a combo reinforcement plate/spacer, as mentioned above.

Thanks for the info. I'm guessing I jumped on these as soon as they were available, so early sounds right. There is only one hole for the vertical through bolt.
I got the driver's side on, which was the one being the real pain, I just need to somehow get the passenger side PVC piece (between the u-bracket and k-frame) the proper thickness. I wish I had run a drill through the k-frame holes like I did on the driver's side. I'm just having an issue getting the bolt to start in the nut - it's barely squeezing through the slightly misaligned pieces. Are the long bolts 3/8"-24? I've tapered the bolt to aide in getting it started, but I'm having a heck of a time getting the 3/8"-24 die to grab the original threads without getting hungry. I think I'll get it after work, just having the issue getting the far end to start, though the front allows the bolt to slide right in easily.

NM, I see it's M10. I got it in, just had to take a little more off shim

If you're Karl, in NH, you bought them in the first batch of Type 6's in '06.
Not sure what PVC piece you're talking about, unless you're using something to shim the u-bracket up off the K-member to get the bolt through. Any reason to not use a floor jack to raise/lower the engine to make things easier? (Just curious if I'm missing something, or not). And yes, the bolts are M10, as you figured out. The original bolts are fine to use, if you still have them. They are tapered and the same thread as what's included with the mounts.

Thanks, I may look for the original bolts although I got the one's you supplied to work after grinding a bit of a taper on the end. Indeed I am Karl from NH - you keep immaculate records :D
What's funny is I was actually hoping these were a little short, for hood clearance issues, so that worked out good. I still have 1/4" clearance even using a 1/2" spacer between the elbow and intake. This allows me to use a N2O plate kit if I desire. :evilgrin: After thinking about what you said above, I think it would be more elegant to add big washers to shim the mount internally vs. what I did, which was indeed adding PVC "plate" pieces that I cut to size and drilled/counter-bored to clear the bolt head and washer. The difficulty was having the u-bracket too high to get the bolt through, so I had to machine the pieces thinner on my endmill (they started at about 1/4".) I was using a cherry picker to lift the engine up/down, so that wasn't an issue, it was just being stubborn whereas if I didn't shim both sides simultaneously, the engine would tend to slide to the passenger side.
Anyway, the engine is down, and I finally was able to retire the cherry picker for now. I'm pretty excited about the amount of clearance I have, though the oil pan is still just barely touching the rack, thus I'm now thinking (since I have the most shim possible under the mounts) that shimming with the large washers may be the best "final solution". If I remove the shims, I'll need about 0.2" - 0.25" added in washers.

I kept track of every set of mounts that I sold.
I should have a stack of those washers in the garage (even after the move), and if you haven't moved in the past 10 years, I still have your address. ;) I can send you a few, if you need them.

I did indeed get the new washers yesterday. :D Thank you very much. I added 2 to the passenger side mount and now there's clearance between the rack and oil pan! Probably make the driver's side the same after I get this beast running.

It's fighting me at every turn. Yesterday I had to remove every Earl's straight AN fitting (4 total) and replace them with Russel brand. After spending 45 minutes trying to get one of those fittings to properly cut into the Teflon tubing, I finally decided that I don't trust the engineering behind these when used with an inner hose (braided stainless exterior) that was too hard/slippery to slice axially with their "cutter" ring (it's just a sharp edge soft aluminum ring, no serration.) Glad Pep Boys sells these fittings and they currently have a 30% discount on many items which made them the same price as online (Summit.) This was one problem of several causing me to fritter my time away, though I could only work so hard with 100 degree "real feel" soupy air. Oh, well. At least it wasn't snowing. :)
