Anyone familiar with what needs to be done to mate a 4l80e to one of these gen v's? I know with the LS swap I had to run that adapter/spacer with the flat flywheel but the gen v crank flange is 8 bolts whereas the LS is 6.

 

Aren't LS9 and LSA's 8bolts? LSA are part of GMs Connect and cruise package. Are the flexplates interchangeable?

 

Didn't think of those. I'll see how that works . Thanks fella.

 

Gen V crank flange is the same as LSA, not LS9, which is 9 bolt.

Happen to know What the LSA guys are doing to run a stock 80e behind theirs?

 

Not specifically, but I bet if you search around, you will find a custom flex plate for this. Check TCI maybe?

Thank a lot man. I'll do some research tonight.

ATI makes an 8 bolt flexplate, shown here. Bob

 

The bell housing is different for a Gen V. The center bolt at the top is offset to accommodate the direct injection pump.

 

I know that. I was planning on using that hole either way. My question was regarding the flexplate to 80e converter and the possible need for a spacer like the LS based version.

 

12620099 is the part number stated on the LT-1 installation manual.

 

Does this flexplate have the correct spacing for the 4l80e?

 

In my case I am trying to mate up a ATI T400/Treemaster converter. John At ATI had a kit 915737 that would work. TCI had one flex plate for a 8 hold application. I dont know if they have the kit. I would call ATI. The other way I was thinking LSA flex plate with the puck for the conversion. Several things to think about and some companies to call. A 4L80E will have two miss matched holes TCI did not have a problem with that. The only other way for all the bolts to line up is a 4L75E with the removable bell housing designed for a gen 5 motor

 

.
Use this part number then. The Gen Vs don't have provisions for a 4l80/85 trans to work with it in the catalog. But I do know the Gen Vs has the same flex plate as an LSA. I used a built 4l65E with the Gen V Bell housing on my swap.

LSX454 engine

 

Yes sir. Exactly what I'm looking for. Thanks a lot

 

Bump to show latest post....
edit- it worked!

 

hmm.. this has me thinking. I wonder how hard it would be to bolt a TH400/350/glide to the gen V's. The new COPO runs a GenV/TH400 combo right? wonder what they're using in that thing.

 

If anyone is looking, i have the flexplate and snout to run a 4l80e behind a gen V block. Never ran, just mocked up. Cost $400. I'll sell for $250 shipped
