Both Mexican made replacement blocks.hmm could either is very hard to see
pulling for the 6

I’ve never heard anything bad about those Mexican blocks.Both Mexican made replacement blocks.
I had a few of them.
Quality just as good as the casting quality on the number.

And I haven't heard anything good either.I’ve never heard anything bad about those Mexican blocks.
Yep just a plain Jane 350. Runs super good though.And I haven't heard anything good either.
My point was no difference between all of them.
They start with 100xxxx they are low quality manufacturing.
I don't know about newer manufacturing now in Mexico but those were a long time ago.
I had some in the 200xxxx same shit.
Nothing to write home about is all I meant.
Hey Martin, you don’t remember me doing this exact swap to my last truck?Just read this thread through from beginning to end.
You don't need to change columns. There is no difference between a TH350 column and a TH700R4 column. The detents you feel when shifting are in the transmission. The only difference is the gear indicator in the gauge cluster. You can swap a TH700R4 indicator out, and put a TH350/TH400 indicator in. Two screws hold it to cluster, and one screw holds the cable to the column.
The reason an '88 R/V windshield is listed as a different part than a '73-'86 C/K or '87 R/V windshield is because in '88 they quit using the windshield antennae. I have seen lots of '88-'91 windshields with the antennae just because someone replaced the original with one that had it. It makes no physical difference.
The reason there is a spacer between your TH350 and your NP208 is because they used those to replace a TH700R4 with a TH350. That way it was the same length, and you did not have to change driveshafts, crossmembers, or shifters.
If I was you, I would flip that ten spline SM465/NP208 and look for an '85-'87/'88 SM465/NP208 or better yet an '89 SM465/NP241. They are a direct swap for what you currently have. You can reuse your current crossmember, driveshafts, and transfer case shift. The only hole you have to cut in the floor is for the SM465 shift tower, and there is a punch out already there. Plus, as you have an '85, all the punchouts are there already for the hydraulic clutch setup, which is a superior setup to the mechanical linkage.
