351W (427W) w/Canton oil pan ishiznitting steering rack 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? Quote Selected

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. Quote Selected

Yeah, somebody recommended using this stuff 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. Quote Selected

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. Can't imagine anything I'd rather be doing to mutilate my 55+ year old body. Quote Selected

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. Quote Selected

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. Quote Selected
351W (427W) w/Canton oil pan ishiznitting steering rack Reply #12 – September 13, 2017, 03:20:52 PM 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. Quote Selected

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. Quote Selected
