4L80e guys, Where to get SFI flexplate for normal 4l80 converter?
Looks like im probly swapping to the 80 in the near future so ive been doing my homework. Id much prefer to get a normal 4L80 converter and jsut buy a new SFI flexplate to match, that way i dont have the custom ls1-4l60/4l80e thing going on with the spacer and all that crap.
Currently im running the CAT Power FP and it was cheap and works great but ill be selling it with my current 4l60 setup.
so where can i find a stock replacement SFI flexplate for a 4l80?

what do you mean a normal 4l80e converter?
I ordered a flexplate from TCI with the wide bolt pattern so I can use a 4l80e converter Circle D spec it out for me. I think that is what you need.
Flexplate LS1 Engine to 4L80E Converter/Transmission Wide Pattern SFI Approved
PART #399754

the spacer is so the converter is centrally located in the crank. it is an extension from the converter to the crank bc it will not reach. This is something I did not know to install so I had to drop the transmission one more time. It is now all buttoned up and waiting for the tranny tune.
good luck with your swap. make sure to measure and make it clear on the side of the harness and also on the rear cooler line.

its really not a spacer. It is actually an extension for the pilot of the converter. this is to ensure that it is centered in the crank.
The TCI flexplate does have thicker mounting points for the converter therefore no spacer is needed, it is becuase of this that the converter will be too far away from the crank to be in the pilot hole which is used to center the converter right on. if you dont use this piece, then the converter will only be secured by 3 bolts to the flexplate with any other contact to the crank, this may cause a mis alignment to occur and a wobboly problem can take out your balance and destroy your bearings and transmission.
at least this is what I understood from the research I came across. I am not too sure about the other flexplates, thanks for posting the differences from those and clarifying what was needed for each one.
I have learned a lot from you throughout this ordeal, I am glad that this board exist to help people like me who like to do their own work....
cheers

Am I right thinking that if I buy this #399754 flex/bolts from TCI ( http://www.compperformancegroupstore...Category_Code= ), that is all I really need for LS1 + 4L80E converter?

oh my bad, mixed up the numbers, I was looking at 399753, youve got it right. I actually have 399754 in my garage, its pretty beefy. I wouldnt be scared to give it 1k at the wheels, I was able to compare it to my SFI 4l60e flexplate and its WAY thicker and heavier, built for power

that was my thought too but after doing a lot of reading, most turbo guys preferred the heavier flexplate because it seems to help spool considerably. enough so that it overshadows the loss in whp. not my experience but its what i gather in general.
