You can only break in the cam and check for leaks. The rings need cylinder pressure to seat - and that means a load. If you blip the gas, it's upside down instantly.

Not the best option but I have a core 727 that I plan to use & I'll lock it up like a transbrake so I can load the engine against the torque convertor to help seat the rings.... I'll probably smoke the trans by the time I'm done but it's just a spare core anyway....

I won't be using it to actually break in an engine, I need a new one for running my mule engine on that I test run restored carburetors with. My current one is an old cobbled together rig that I'm not happy with.
Scott I built the one in this video for under $100 in steel, casters and half a day on a Saturday cutting and welding it up.....it's very stable and doesn't walk around at all.....plus it's very easy to roll with the casters.....something like this should get you where you want to be cheap....no reason to spend big bucks on a commercially made unit IMO

My good friend built this. It does not flip over when ya hit the gas!
My dad and I built one very similar to Scotts71chall, only it doesn't look nearly as nice, lol. It works great though and doesn't even come close to flipping over when you romp on the throttle. Last motor I had on it was my Indy headed 440 that makes close to 700 hp. I just use an old cast iron 4 speed bellhousing and flywheel. It was worth every bit of time and effort we put into it. Built w/ scrap we had laying around. Retorquing heads, swapping valvesprings after cam break-in, fixing leaks, and any other problems that come up...much easier to fix on the stand rather than in the car.

Around here there are tractor dynoes, and they are a water type load device that hooks to the pto. It could be easy enough to adapt the PTO to a flange or a yoke to hook to the tranny, wouldnt think it would take much at all. Im sure if your around an implament shop they would let you use the dyno. We were able to use the one from a local shop, and tried this on an irrigation engine I rebuilt.

Hmmm? Maybe a Boat Prop in a barrel of water connected to a shaft that bolts to the fly wheel or some kind of U-joint??? Just some ideas.

Heres the one I built last winter when I needed to run a couple of motors. Bought only $25.00 worth of iron to go with what I had laying around. Ignition, fuel, and rad were left overs. Have more in gauges and switches, but hey, it had to look nice. Casters are off of the toolbox in my trailer. It does not scitter around floor, gauges dont vibrate, and it DEFINATLEY doesnt flip over when you blip the throttle. Had a stout blown SBC on it and it didnt flip it. PM me if you want some dimensions or tips. Depending on what you have laying around and going a little less expensive route on gauges and switches, a person should be able to build a nice one for way under $500. Jim
