Hi, this is still fun to read.... Sorry i don't have any riveting info to add, but i think the L99 had 588 stamped into the block and like you said 327 in the LT1 block.
We have stuff like this happen in Chicago, so I can only imagine what it must be like in places like Arizona.The pavement gets so hot here in the summer that the tar in the road melts and sticks to your shoes!
I am signing up for the 2021 ISSCA Nationals in western Michigan. I went to the 2020 Nationals just for a day due to work and family commitments and had a blast, even in my minivan.Any long-distance plans for the Impala? It's fun to see well-kept "old" cars with out-of-state tags on the Interstate.
Oh yes. As a guy who used to live in Syracuse NY, anti-seize was mandatory. I bought stainless bolts for the converter to exhaust pipe bolts, but interestingly the threads were much looser than the regular non-stainless grade 5. They held, but the difference in clearance was noticeable.Are you using anti seize on the manifold to converter studs and the converter to exhaust pipe bolts?
Odd question:Maybe this is a redundant post; if so, I'll delete it later. The new steam pipe came with the little seals on the lower left. Apparently they are prone to leaking; the tribal knowledge solution is to replace them with Dorman oil drain plug seals, part number 097-025. You'll need four. You could also build your own steam pipe, but be aware that the thread on the heads is NOT tapered like pipe thread, since it's banjo bolts flowing the fluid. Given that Keen Parts sells these for around $90 plus shipping in the US, and they took a lot of coaxing to fit, I may just build my own next time.

Does trimming make R&R easier?Before we get too far away from the transmission install, the '94-96 factory crossmember was tricky to remove early in these cars' lives, but since the body mounts have compressed in 26 years, it's usually squished between the frame and the body. I used floor jacks and lots of wood to lift the body slightly. This gave enough room for crossmember removal and installation. I also trimmed the outer edges and then repainted them. They are not carrying any load out on these corners anyway.

Yes. If you've had to remove one, you'll know why I trimmed it. I trimmed other edges as well. As far as engineering, if you draw the load path, it doesn't go through those outer edges (as far as my judgment goes).Does trimming make R&R easier?
For some reason it makes me nervous cutting so close to that hole. Isn't there some sort of "engineering" behind the bends in the steel?
Is that Dorman part number for OUR drain plugs?Yes. If you've had to remove one, you'll know why I trimmed it. I trimmed other edges as well. As far as engineering, if you draw the load path, it doesn't go through those outer edges (as far as my judgment goes).
As to the steam pipe seals, you need something that confirms to everything else around it. Copper washers might work, like how they are used between brake hoses and calipers.
