Beveled 5.3 liter flexplate
 

i figured out i have a beveled flexplate with the 3 bolt pattern, and im serious about swapping it maybe with a different one, but have heard you need spacers for a flat one. im confused. the bevels stick out like its already spaced for this tranny, yet i see alot about these trannys having to have the flexplate or torque convertor swapped or a spacer put in. this is all very confusing

SO i did some carefull research. and i got the name of the flex plate wrong. i have a dished flexplate. could this be bolted up to a 4L80E? and if so will i have to have the following shown in the photos? also that isnt my engine in the photo, except its a matching flexplate.

heres a photo of my TC. but its the 6 bolt TC.
sorry, if i had a better pic, you guys could see it better

yes....you need a 6 hole flexplate for an 80e. I bought a "older generation trans" kit from Pace that had this flexplate and the spacer. I had used this for a 200-4r which needed the 3 holes on a tighter pattern so I just drilled them. When I pulled it, the flexplate wound up working out great for my 85e.

Nice! I figured the dished one will have to go any way. any one got any problems with the ATP spacer and flexplate for $63? http://www.summitracing.com/parts/at...make/chevrolet

think I got this one from Pace before Summit came out with the one you show......this shows 11.75" tho... vs 11.5" bolt pattern specs yours show?

Hmmm.. I think pace is the way to go

68GMCCustom that is a crazy looking flexplate. I've never seen an LS flexplate that looked like that.

When I bought my Yank converter, they hooked me up with an LS/4L80E swap flexplate that works great. No spacer needed, and it's SFI approved.

Re: Beveled 5.3 liter flexplate
 

Yes its strange looking and looks too weak to me...and I should probably be running SFI flexplate. Looks like it would be twisted into a pretzel in between my cam'd up big headed 6.0... and my 4L85e. :lol:

Thats what I need to do is call yank...my convertor was supposed to be 2400 stall but is stock. I need like a 3k or so stall. I've just been putting it off because of a upcoming wheel/tire purchase. I've understood that you can get the "spacer" issue worked into the convertor too...so it wouldn't need the spacer.

Re: Beveled 5.3 liter flexplate
 

Ahhhh, now that you mention it, that is what I've got....lol. Then I got a "regular" LS SFI flexplate from them.

Forgive me, it's been a few years :ito:

I purchased the ATP flexplate.. Think summit has made an ERROR on the dimensions. but it looks just like yours!!
