The parts from Danchuck arrived, they are almost identical to the old parts, so the 4 inserts in the new kit will not be used, as the old ones are still in good shape and are pressed into the steering arm and the drag link.
The one exception is that the bearing adapter on the bottom of the idler arm at the frame has a grease zerk on it, the new parts do not, but this grease zerk hits one of the header pipes, so I pressed it out and rotated it 90 degrees or so toward the motor so it would clear the header pipe, and pressed it back in....
Cleaned up, fresh grease and new bearings on the frame mount end, now to do the drag link end....
More Later...
Update,
Discovered that the drag link at the idler arm does not have a grease fitting, so am drilling and tapping for that, here's some pix....

The March Performance parts showed up, this is the install diagram:
Here's the parts that came today (below), there's only one set of idler rollers, there should be two, let's see what March says about this, I can't make this work with only one set of idlers, look closely at that diagram above....

Played around with the power steering pump orientation, started out with this as indicated by March Performance:
But there are obvious problems with the hose connections and the a-arm mount and the header tubes...
so tried this:
Still have hose problems with the alternator and the header tubes...
so tried this:
I can make this position work....
Improved the alternator mount, as for some reason MP sent me
an extra adjustor rod adapter, so I used them both....
And changed the mount for the AC compressor to this:
Spacers will be added on that bolt each side of the adjuster rod...

Got some more work done....
Had to do a bit of remedial work to correct some deficiencies in the way these MP brackets were set up, and had to wait for some parts that were not shipped with the initial order. But I'm pretty happy with the way the setup is turning out.
Still waiting for the new Corvette style LT1 flanged crank hub to arrive from ATI to replace my Camaro hub, which will relocate the damper further forward and align it with the MP LT1 "Outward Mount" pulley system.
The Camaro LT1 hub I'm using here is temporarily located in a forward position in order to facilitate the fitting of these other MP components.

Meanwhile, ATI sent the wrong hub for the revised crank damper setup that I need....
My Camaro LT1 hub is on the right, according to ATI that left hub is a blower drive hub for a small block Ford, don't think I can get that to work here...
That's the Ford hub on the right in this pic....
Larger OD crank snout, different drill pattern for the damper mount....
The give-away was this part number on the new ATI hub, ATI says it is a ford small block blower drive hub....
But the box it was shipped in had the correct part number on it for the flanged hub I need for the Corvette LT1 motor...
So now I have another delay while I ship this part back and wait for them to ship me the correct part...

Finally got the correct ATI Corvette LT1 flanged crankshaft hub for the damper today. It is quite a bit longer than the Camaro hub...
The holes were all in the correct location, and the damper bolted up to the hub correctly....
Now to see how well it aligns with the March accessories mounting system...
Aloha,

It turns out that this new ATI LT1 flanged hub is seriously too tight for the crankshaft.
As the older ATI LT1 (Camaro version) fits normally with no problems on this crankshaft snout, the problem is with the ATI hub.
Right now I have a broken bolt inside the crank from trying to install the assembled damper with the new hub, and a stripped damper puller from trying to remove this hub after breaking the installer bolt.
I've had this damper puller for many years,
it takes a serously too tight hub to cause this center bolt on this puller to strip the threads like it did on this one...
Here's some sketches from the first install attempt, showing that I still needed to go about another half inch to get it on all the way, that's why the crank pulley didn't line up with the accessory pulleys...
Now I have to disassemble the damper from the hub, and heat the hub to try to loosen and remove it, and then remove the broken bolt stub from the crankshaft...
Am I having fun yet???

It turns out that ATI is making the latest "Super Damper"s with an "undersized" interference fit, requiring a machine shop to hone to fit on a Sunnen rod hone.
Here's an excerpt from a document on the ATI web site...
OK, a visit to my local machine shop on Monday...

Here's the bolt that busted off in the crank while trying to pull the damper onto the crankshaft snout...
That's a grade 8 bolt...

Today:
Quite a few hours with #100 gray wet/dry sand paper, then smoothing with #600, took out about 0/0008" to 0/0010", then did an assemble with just the flanged hub and assembly lube....
assembly lube on the 7/16 sae threads inside the crank snout also, used a 5" by 7/16" bolt and kept adding spacer to push this on, tight but not abnormal in my experience...
Update:
The balancer is now back on the hub, the serpentine belt is back on, and everything lines up just as it should...

Had to drop this project for awhile, some health problems, and I managed to break my left arm, kinda slowed me down a bit....
As my arm gets stronger, and I'm feeling better, I'm starting to get back onto the '55 HT project...
Lookin' closely at this front setup, and noticed that the power steering pump is slightly out of alignment, with this March Performance setup I bought...
The pump sits about 1/8" too far forward....
It sits just below the alternator, and closer to the motor in this pic...
These spacers, 0.316" thick, came with the March Performance LT1
setup, but they are obviously too thick for this particular setup with
these particular heads and block. Everything else seems to fit just fine
now that I have the dampner problems sorted out....
I had a variety of allen head bolt length available to get
a good fit with the proper spacers....
Picked up a dozen ss flat washers, these are 0.050" thick....
Behind the idler rollers and bracket, is the bracket for the PS pump,
that's where the spacers have to go to align the pump....
I started with two washers, 0.100" spacing, wasn't quite right,
added another washer to each location, 0.150" now....
It looks good, don't think I can get it much closer....
