77 K10 LS Swap
This happened 2 weeks ago. I managed to get it all back together last Monday. Been lightly driving it to work all week, checking the differential temperature when I get to work and back home. Temps have been between 135F and 160F. I am really happy with it so far.- Madhorn

Bad day leaving work. Thought at first the NV4500 transmission was the problem but after running it on jack stands and putting my hand on the differential, I could feel the ring and pinion not playing nice.- Madhorn

I did have to put a small dent/notch in my cross member to clear the oil pan. If I remember correctly only on the drivers side.- Madhorn

Fingers crossed. My 5.3 bottom end has 241k on it. I did put a new oil pump in it when I did the swap, then added .100 worth of washers to the pressure relief spring in oil pump when I did the cam swap. Oil pressure went from 40 ish to 55ish.- Madhorn

I paid $600 for a street tune. No shift point tuning here, 77 is manual. Sorry to hear about the spun bearing.- Madhorn

It’s been 6 years since completing the LS swap in the 77. The engine has seen some minor upgrades over the years like a cam, headers, and intake tube. I have played around with tuning myself using a HP tuner set up. The truck has always run well with some occasional idle quirks but good...- Madhorn

After a 200 mile duck hunting trip today, the 77 rolled over 60k miles since the LS swap. I have throughly enjoyed every mile and would definitely do it again.- Madhorn

Alternator went out Thursday on my way home from work. Luckily I made it home without issue. Installed an alternator from my parts pile. Back up and running.- Madhorn

The right rear brake light and right turn signal quit working last Saturday. I figured it was just a bulb, but a new bulb did not fix the problem. After some troubleshooting I figured out that the turn signal switch in the steering column was the problem.- Madhorn

Dang. Another project followed me home yesterday. 69 Chevelle to go with my 69 C10. This is going to be a long term project, it’s currently nothing but a rolling shell and needs quite a bit of sheet metal work. Luckily, like our trucks, there are lots parts available. Just takes $$.- Madhorn
