if i have my transmission and torque converter removed, is it ok for me to start and run my engine to watch my flex plate and ensure that it does not have any "wobble" to it?

Yeah, we started a 350 on the stand with nothing attached. No flexplate, exhaust (open valves /forums/images/graemlins/shocked.gif) just for a second to see if it ran OK. I was standing in front of it and the fan pulley flew off and went between my legs. Missed the twins by .0001"

Do you have an engine mount that I don't?? Secure the motor well or you'll bust/bend the distributer! /forums/images/graemlins/thumb.gif

Take all the precautions you can think of and DO NOT get rev happy . Your motor will rev FASTER than ever before due to lack of converter weight. Beacareful not to kill your motor by over reving of reving to quickly !

What are you supporting the rear of the engine with when the tranny is out? Why not just remove the flexplate and check it for warp, by laying it down on a flat surface, or just replace it all together. /forums/images/graemlins/thinking.gif

I would not recommend you do that....take the plate off and check it if there is any question....also how is the back of the engine supported..???

a couple of you are asking how i am supporting the rear of the engine... i am not sure yet. my tranny install instructions state that i need to support the rear but tell me not to place a support under the oil pan. there are a few areas that i can get a bottle jack into but this will not work if i am going to run it to observe the flex plate. at first, i did not realize how inexpensive the flex plate was (35 to 45 bones). i am working with a 95 crate motor; if the flex plate looks flaky in anyway, i am just going to replace it.

/forums/images/graemlins/doah.gif I don't know why I said that. /forums/images/graemlins/doah.gif Flexplate was indeed on, but nothing else was. And yes, it was very freaky, and my dad and neighbor pissing their pants laughing didn't make it any better. /forums/images/graemlins/yikes.gif
