Running Engine on engine stand
 

My engine is a Reher-Morrison 555ci. BBC single 4bbl appox. 900hp. Is it ok to run my engine on an engine stand without the trans. and rev it up to like 6 or 7 thousand RPM? Or will it rev to the moon and not stop?
Or do I just have to let it idle or maybe can I take it to 2 or 3 thousand RPM?

You can do it BUT just dont get to carried away reving it up.
On a stand or unattached to a tranny engines rev up VERY easily.

Why would you want to rev it that high on the stand? I think you are asking for trouble. I've started them up on a stand that I made for that purpose, but never free reved one to 6 or 7000 rpm! JMO

I agree!! It's pointless to rev one that high anywhere except on the track

He probably does the same thing in the pits and at the line. So hey, why not do it on an engine stand too?

I don't reccomend doing it on an engine stand, because of the center of gravity is rather high. I have a home made test stand and I always crank my engines before installing them. Break in cam (if required) and check for leaks. They can be eased up but not hossed, if you know what I mean.

I have a well braced engine stand that won't tip,you might as well say its similar to a car frame.

I never buzz 'em up that high without a load on 'em. That's what a dyno is for.
Still it'd be interesting to hear any real scientific/engineering opinion on this........ :D

I would be scared that the rotational force would tip it over :oops: :oops:

No offense, You must be nuts........

If you have any type of power you could find that engine your playing with in your lap.

I do not think an engine stand was designed for this application, But what do I know...... :lol: :lol: :lol: :lol: :lol:

No offense, but about 20 yrs. ago i did exactly what you are talking about, i put a 540"blown alky 1471 Littlefield motor injection flowed by Ralph Gore on an engine stand. I bolted the stand down with 1/2" concerte bolts. Let it idle until the temp came up on the solid heads. Cracked it a couple time and it pulled the lugs out of the concerte, almost turned the engine stand over, learned my lesson real fast. The motor did later run 6.77 @ 217 at Bakersfield, not bad in 1987.

I wouldn't want to be standing anywhere near a Big Block at 7000 rpm with no load....
