Did they understand you were mating to an LS engine? Is it the correct part in other words...

Actually, I thought so. I thought I bought the one specifically for TH400 to LS. Turns out that I screwed up. I bought a 92451. There is a 92451 LS. It looks like the only difference is that the 92451 LS has an extra tab for the top center bolts on the LS block. Damn! This should NOT make a difference in terms of the flex-plate interference. Next time I have it out, I'll weld a tab on the top. NBD.

J.W. confirmed that the only difference is that the LS model comes with metric hardware and the extra bolt tab. So I'm good.

I really like the ball and flange collectors! I had to ding the passenger floorboard a little to clear the O2 sensor. Probably should have taken the header off and tweaked the bung. Oh well, hit the easy button instead.

Just installed ICT Billet brackets for alternator, PS pump, and tensioner. They are top notch! Only minor gripe is positive stud is very close to oil filler neck on valve cover. Will cut stud down accordingly. Haven't bought PS pump yet. Have new GM pulley though.

You could change the clock position of the alternator...

Didn't think of that. I'll take a look. It came with a Alternator battery post kit #551900. No instructions though. Just pictures. Not sure what the deal is. It's just a bolt and a aluminum spacer. I can cut the stud down a little and it'd be fine.

Not much progress lately. I have the accessories all mounted up. Will plumb the PS pump next I guess. The interior is completely gutted including the dash. Gotta paint the dash, treat and paint the floor pans, and sound deaden. Then I can start wiring the whole car. Plus I'm building a cabin and about a dozen other things. Ugh.

Nice work!! Looking good. Power Steering. I used 98-2000 f body pressure line. Just had to replace metric end with oem flared end. Tweek the hard line section to line up at gear box. Easy!!

Thanks! Thanks for the tip on the pressure line. I've been looking at the pieces to run braided line. I like simple and cheap though.

I installed an F-body high pressure hose like suggested. Not thrilled with how it looks. But will work for now.

I couldn't take the factory style pressure line. I Fabbed one with Russell Powerflex and associated AN fittings.

I chipped the first POS plastic pulley when I was tightening the pressure hose. Barely bumped it. Had to cut it off. Puller ripped the flange off and it still wouldn't budge. Bought a new one. It wouldn't press on. It seized up just short of going on all the way. Ugh! I bought a billet pullet this time, Put the pump in the freezer overnight. Put the pulley in boiling water. Greased the shaft real good. Went on like butter! School of hard knocks in session again.

Then I decided to test the system before firing the engine. Cut the head off of a bolt and used a drill to spin it. Works perfectly! No leaks. Turn the input shaft by hand since the steering column is out. Lock to lock smooth as glass.

The pump pulley is meant to be a dry interference fit to keep it on the shaft. Using grease on the shaft is questionable. The pulley may come off easy as "butter" too. JMO

I'll have to disagree with ya on that one. A proper press fit isn't going to come apart because lubrication was used to assemble it. The lube just ensures that the metal doesn't gall and seize up. But I also added a retaining bolt with lock washer and blue Loctite. I guess, even though I disagreed with ya, I was a little concerned. Lol!

Made some more progress. Fuel lines are done. I pressure tested those to 100psi. Installing 1/2" & 3/8" stainless lines was not fun! Is overkill. But planning for much more power later on. Had to replace the Strange master cylinder that was leaking.
