Hey. PLEASE do a build thread. Your 284 swap thread is killer, and it would be amazing to see this swap in the same detail as your 284 swap is, from fitting into the engine bay, building the mounts and wiring! I'd love to see this process as it's a swap I'd love to do with my cutlass but I don't need an engine right now and afraid to remove my engine to see it not fit into the engine bay. So thank you for pioneering this into a 1/1.5 gen w-body! However I have done some research in the past which may help you out. In my research for how to do an LS4 swap with manual trans (was going to use the F23 with Fiero Guru transmission starter mount bracket) I came up with this. - Use an LS1 flywheel and cut the diameter down to fit a 142 tooth ring (Part# Pioneer FRG-142W) on it, drill and tap the mounting holes for the pressure plate and then use whatever clutch for the trans you're using. Apparently the stock thickness of the LS1 flywheel will work no issues with the clutch and trans. Alternatively there was a fiero guy who got a custom flywheel from LSC performance (http://www.lscperformance.com/) to work with an F23 trans. Since when using a F23 or getrag 282/284 with a 3800 the flywheel is the same, I think this would work. - you will also need to build a new support bracket for the intermediate shaft (I'm sure not an issue as you built one for the 3800/284 swap). Unfortunately I have no real world experience with this, but I had heavily researched this and made notes for the future before realizing the possible size limitations in the engine bay. Best of luck with this! I'll be "cheering you on" from a distance!
