more baby steps.... relabeled my zip lock bags (originally did sharpie right on the plastic, it was wearing off, so re-did on maksing tape). Got the parts are lined up on my harbor freight cart (BTW, this little cart is pretty handy! Would recommend for anyone who likes to wrench in the garage). Found some pieces that needed cleaning and painting, so took care of those. Got the first few pieces attached to the long block (yeah!). Also tested my t-stat....and it works!!! who'd a thunk? Had to order a new cable for it...and a bunch of other misc stuff. My goal for next weekend is to get it completely prepped and ready to install.

Anti-seize the engine tin screws!
Test fit tins before assembly, and straighten so they fall into alignment where the screws just slip in and start. Stressed tins crack!

Thanks for the tip ... wouldn't have thought of it, as I never had problems getting them out (probably because with all the oil leaks it used to have, it kept all the tins nicely lubricated. :flower: ). Most of the tins did fall right into place (i took pains not to bend when I removed them).

For the rest of the forum, learn from my mistake....don't forget that pesky little gasket that goes on between the oil cooler and the tin. I had all of the sheet metal on, alternator, dipstick, etc and realized I forgot it. It took me an hour to take everything off, install the gasket, and put everything back on.

Next up is exhaust installation. Picking out the best of the worst from the two exhaust setups. I do have a brand new LH heat exchanger that I bought 15 years ago that will get installed...going to take a gamble on one of my used RH. If it's bad, shouldn't take more than an hour or two to R&R. I figure at $329, and relatively low effort to replace if bad is a safe bet.

Spent a good 30 minutes with a file sanding the exhaust manifolds flush, also wallowed out the holes a bit on one to relieve tension on the exhaust studs...might pull it off and do this a bit more, as the fit is tighter than i would prefer.

And then, here is my Dilema. I bought a new left side heat exchanger 15 years ago, but never got around putting it on the bus. I have two complete stock exhaust systems, however, after I've inspected both, I'm not sure/can't tell if I have a good right one. None of the exhaust elbows are great...all four have bowed flanges from over tightening. So I was thinking, if I have to buy a left side heat exchanger and two new elbows at $100 each, it would be about the same as converting over to the the simpler system from 73/74. Neither option is cheap. So I took a grinder and a flat file to the elbows to get rid of enough of the bow so that I should get a decent seal, and I'm going to bolt up the better looking of the two used manifolds. If I get lucky, and it doesn't leak, bonus. If it does, I can replace the exhaust fairly easily

The 72-74 system is definitely superior. Heat exchangers are one thing, but the hard part might be the proper tin. I haven't looked since I converted mine (can it really be 14 years ago?), but I felt lucky to find it way back then.
Truth is like poetry.
And most people fucking hate poetry.

Thanks for the heads up.....didn't even think about the engine tin. Guess I'm stuck with what I've got.

On a side note, I ordered new heater tubes (go from the exchanger to the heater control box) from CIP1. Really impressed with the quality, however, both ends of the tube are round, whereas the the original is oval where it fits onto the exchanger. It's going to be fun doing that myself.
