thanks Bear, i'll make sure that gets done when things come together on the new powerplant!

 

glad you got it figured out David and it wasn't in the engine.

 

Honestly all things led to something besides the engine, the noise wasnt there, ( the kind you would suspect) but when you cant find what youre looking for it really gets annoying, i knew in the back of my mind it wasnt the rotating assembly, BUT damn like i mentioned i ( we ) couldnt find it, what led to the tear down and pretty much said ok lets pull it was the fact we unbolted the torque converter from the flywheel and when cranked it still made the noise, i even checked play from the torque converter to the flywheel but didnt check rotating end play, moving it back and forth in the vice versa rotation, if i would have done that i would have not pulled the damn motor lol!!!

what was really bad is i borrowed a 15k dollar piece of equipment from work, basically checks vibration and analyzes noise waves and such, which pointed to the bottom of the motor inside the oil pan and actually at the rear main bearing lol!!! just wish i had gotten the pointer end instead of the magnetic end..

oh well, just glad like mentioned it wasnt anything serious on a good note the pistons showed up last week, so the new power plant now being put together should be ready for install end of next week. gotta finish up the direct port and should be done..

 

No problem, I'm just glad isn't wasn't anything internal and like you said, you can set it on the shelf and have a spare bullet or at least it's still worth something if you did decide to sell it later.

While I have no particular problem with the TCI flexplates, hell they were the only thing available for a long time, I wished the Circle D or the J.W. units were already out when I purchased mine. I have it setting on the shelf and while it probably wouldn't do any good what-so-ever to go with another brand, I may do so anyway.

Most people don't know the J.W. flexplates are even available. Below is a little write up on them.
The J.W. Performance flexplates, “The Wheel” is now available for LS1 to LS7 engines, LSX, LSA and LS9 engines. These flexplates fit the GM Powerglide, Turbo-Hydro 350, Turbo-Hydro 400, 700-R4, 4L60E, 4L65E, 4L70E, 4L80E and 4L85E automatic transmissions. This beauty is made from chrome moly steel and is .187” thick. “The Wheel” is dish shaped in the crank area to accept various style torque converters. The flexplate provides proper clearance for many applications and will accept 10.75”, 11.08” and 11.5” torque converter bolt patterns. For those applications with extreme horsepower a flat flexplate is available with the use of a crank adapter.

 

my torque converter is smaller than mentioned lol

is there a site i can visit to check these out? maybe get more info

How do the bolt holes on your flex plate look? They oblong now?

 

bolt holes look fine.
