LM4

[sdeeter19555]

I had one of these...it buckled with a dressed 440 hanging on it. Apples to oranges, but definitely not 1000 pound capacity. The 440 fell hard enough to put a crease across the oil pan...

 

I ended up modifying it and welding it solid with extra bracing to make it work.

Well the LM4 is an aluminum block

Nice thing about modern small blocks... they can easily perform like old school big blocks, at little more than half the weight

Wasn't arguing that, only that these 1000# stands won't hold 1000#s...

Agreed. I would likely not have put an iron block engine on this one.

At such time that my engine is not on the stand, I will be upgrading all of the fasteners to 8.8 or 10.9, possibly welding it together.

In the midst of jacking around on my 11 hour Saturday, I realized that I have no hole for an oil dipstick in my LM4 block. Now I am debating about buying the AFXtech LS7 dipstick drill guide for 80.00, or just not using one.

Who am I kidding? I'll get the tool and drill the darn hole for the dipstick tube.

Think I will get a Kent Moore J-42386 too...

Not familiar with that engine, so tell me how are you supposed to check the oil with no dipstick?

[gmfan24]

Dipstick attaches to the oil pan on a trailblazer.
