LS engine run stand

[StolenFox]

Thought I'd post some pics of the LS engine run stand that I'm building. The LS engine will eventually find its way into my 83 BMW 533i (currently running a 5.0L Ford and T5 manual) with a T56. Engine is a Iron LS2 with milled LS3 heads.

mmm 6.0 or? looks to be. Lq9 most likely

I would recommend more bracing to the mounts rather than just one bar. Small streetbike engine would be fine but that thing has far more torque. Would at least gusset it. Looks good so far though.

Very cool, and with the throttle by wire pedal mounted. Any plans to add a radiator?

Looks like the stamping says 6.0 and looks like an iron block, lq4 or lq9 sounds right... but i havent been keeping up with all of the engine stylings lately

Thank you. There will be cross bracing to the rear mounts (fronts are beefy and are not going anywhere) and I still have to build the load bearing rear exhaust hangers. I needed to figure out how to use the 2010 Camaro SS mufflers before finalizing the mounts.

It's not a LQ4 or LQ9. The block is a gen 4 Iron (L96) 6.0L that I've turned into a LS2/LS3 hybrid using LS2 flat top piston and rods, LS2 cam, LS7 lifters, LS9 springs and LS3 heads that have been milled .030 to pick up the compression.

Thank you. Yes, I'll be adding a radiator with electric fans and EFI fuel supply system. I was thinking about one of those boat fuel cells used with outboards and an inline pump with the C5 vette filter/regulator.

The tq generated will not damage the mounts as is. I've run hot 350's just laying in a tire. There is nothing for the engine torque to react against. It barely rocks when you wing the throttle.

Awesome, ill be building one soon for a Jeep 4.0.

Looks good, but what is the point of building one? Just to see if the engine runs?

cuz he can? to see if the new engine has oil pressure and doesn't knock its *** off before going through the hassle of installing it?

This is the first engine I've built 100% from scratch and I want to make sure it's good to go.

LOL, cuz I can is definitely part of it! The biggest reason is this: The BMW is running just fine with the 5.0L Mustang setup and I need to sell that drivetrain, EFI harness & mounts to buy the T56 6-speed I'm going to use with the LS2/3. Much easier to get top dollar for the Ford stuff if I can take the buyer for a ride. Moreover,since everything is custom built for the swap in the BMW and nothing just drops in I'd hate to tear apart a great running car for a swap to a untested engine.

Here's the car as current:

That looks awesome. Its nice to know everything works before putting it in the car. Nothing like firing up the engine for the first time!

Or if you get you a$$ kicked by an oil leak you put it on a stand. 327 in a 32 Ford

I see alot of cool engine run in stands and have even used one that my buddy has. One problem they seem to have is cooling. It takes at least 20-30 minutes of running to break in a hydraulic cam and its hard to keep the engine cool for that long. Now to the question... What are those cooling towers they have on dynometers and how do they work??? I've never actually seen one in person so I'm not sure how they work. They must work better then radiators and fans.

Very impressive, that looks like a pro quality stand you built. Motor sounds great.
