Re: 72 K30 Build
Been following your project for awhile now, it's really starting to take shape! Are you going to run your engine in the original 4x4 position or move it up to the 2 wheel drive position? I'll be starting a similar project soon with my C/30, been gathering parts for several years and have about everything I need now.

Re: 72 K30 Build
Thanks Blazerman, thinking the forward 2wd position to make a big block install go easier.

Looking good keep up the work. I think it took me about a year to get it back on the wheels.

So I borrowed an early style motor mount from a friend who only had one. A block of wood was subbed for the other side this is some high tech stuff here! With the K35 trans mount just set inside the frame rails and no TC mounts we got pretty close to carb level just messing around. Left exhaust manifold is touching the cross member but I think the new poly mounts are thicker.

Re: 72 K30 Build
If the poly mount isn't tall enough, you could always shim the engine up if you had to to clear the cross member.

Both the 73 K5 and the 84 K35 stands we have are for a small block, the motor mount take 3 bolts to mount to the stands not 4 like the big block version. I'm thinking ours are the short/wide you describe and have noticed that our later K35 version does seem to be a little heavier duty with extra mounting provisions to the frame and cross member but are still pretty much the same overall dimensions. Quote:
While waiting for the new motor mounts to show up we’ll get the crossmember mounted and start to figure out how we will mount the sway bar. Really want to run the original front cross member if possible and these later sway mounts are not helping that goal as much as I’d like. So, so close but no cigar! ![]()

Re: 72 K30 Build
That is a good idea for mounting the sway bar. I just might have to do something like that.

Re: 72 K30 Build
That is a great idea. I may have to alter the tube a lot due to my front cross members being modified for inline 6's.

Re: 72 K30 Build
Here's another reason I wanted to stick with the original front cross member. I’ll tell you what these blazer steering box supports don’t fit the 133” or 157” frames real great. But with a little trimming it’s going to work out just fine, still need to add an upper shim to complete the fitting but you get the idea.

Re: 72 K30 Build
Our new poly mounts and bushings are here. First thing the rear spring bushings were swapped for the correct ones, way better fit. Not too excited with the washers that came with the new motor mounts though (wimpy). Pretty sure I've got the correct (beefy) old style ones in my nut, bolt & washer collection.

Re: 72 K30 Build
The later K35 trans/tc cross member is going to be the cleanest and easiest to install by far. Here are some pics of prepping and installing ours it had a small chunk missing from an earlier driveline failure as well as needing some straightening.
The original 67-72 style member would have required a pedestal to fit the larger longhorn frame section. It could be done but I felt it would always be a battle to work with and not worth the extra effort.

Re: 72 K30 Build
Thanks DW!
It's time to install the tc and side mount. Couldn't locate the exact right length (they are really, really short) bolts from bracket to case so we just cut off the extra to make ours, no problemo. ![]()

Re: 72 K30 Build
Our rear pinion angles look close enough for me, tc 2.5 down & diff 1.5-1.75ish up, roughly 1 degree or less off the same plane. With the angles that good and we like the overall stance the rear most hangers did get bolted. Went ahead and finished mounting the sway bar to the new mounts. Sway bar looks pretty flat with the motor/trans/tc weight in place.

Re: 72 K30 Build
Thanks for the kind words it’s pretty cool seeing it start to resemble a truck again!
We built a new high lift type cab lifter much more stable and just in time to fit the cab with some new body mounts. Our mockup big block fits great, plenty of room in the forward 2wd position.
