440 engine dyno break in

[Runningman20]

Now that my car is back I'd like to have my engine broken in and tuned on a dyno if possible. I'm not an engine guy so any advice would be appreciated. I had an engine buddy of mine do a cam change and disassemble everything, boil the block and reassemble. It's been sitting for 10 years or so, I cranked it occasionally while priming probably half a dozen times since. I also loosened all the rockers. Also does anyone know of a shop in SE Michigan that does this? I'm in the Romeo area, thanks!! Matt

Seeing as it’s been sitting for 10 years I’d recommend getting an engine tear down gasket set/kit and to disassemble, inspect, and re-lube, and reassemble before starting it the first time, especially when they’re going to Dyno pulls right after run in.

Seen too many threads on here where a guy wipes a cam from starting the motor that has sat for 10, 12, 15 years etc....

You'd be really lucky if you don't get oil leaks. I chased oil leaks forever on a 440 that sat for only a few years. If you don't want to tear it down at least you are doing a dyno break in. You could get lucky and catch all immediate leaks before installing. Don't forget the break in oil.

Thanks! I got in touch with the guy that did my engine and he's gonna tear it back down and check everything out. He also has an engine stand so he said he could run it if I could come up with some headers and bellhousing so I'll be looking for these, he's a Chevy guy.
