As I said above, I used a stock LT1 F-body flywheel. Any direct replacement thereof, would work fine.

Toms suggestion is probably a lot more cost effective

Yea now that I think about it that would be a better idea but my only concern is that I wa searching the web and it seems there hard to get a hold of.(I'm probably wrong) but if I could get my hands on the stock flywheel I would do that ( who doesn't like to save money ) but if I can't I was just wondering because you guys said the stock one had to be modified to fit cause of the the 2pc RMS so would the aftermarket flywheel I get (if I can't find a stock one) would it have to be modified also ???

That is correct; if you get a FW that is FOR an F-bod LT1 application, it will need the same modifications that I mentioned earlier; neutral balanced, bolt pattern drilled, and hub enlarged.
Is there a FW that works with an F-bod LT1 cluch/trans and bolts to an older 2pc RMS crank? Probably, but I haven't used one, so maybe cuisinartvette can fill in here...

only ones I know of are aftermarket the bolt pattern is different flange depth I think also. Not sure if a stock one can be modded or not
Aftermarkets are a few hundred bucks easiest way Id guess if you cant find a LTx piece. Gotta be some on ebay or craigslist Get it surfaced and go.

Here's a thread over at ThirdGen that lists current manufacturers of the 2 pcs RMS flywheel for LT1/T56 applications. http://www.thirdgen.org/techboard/tr...-flywheel.html

Tom400, Good to hear that you've had your LT1 flywheel modified. I've heard this done (once) before. I'm not sure I could find a competent machine shop around here that would do it for $80 though.

I was worried when I had them do it, that they wouldn't "get it" and they'd screw it up. But they didn't. They did a good job and it worked.

Ok so I know I asked this question but I didn't get a response I need the c beam bracket and the only people to do this (that I know of) are
https://www.google.com/url?sa=t&sour...10kXFehhMRuGIQ

But for some reason the page won't load on my phone computer it anything.

I was wondering Is there anyone else who make them??

And if we're to have one made were cause I get the "specs" of what would need to be made??

Thanks for your time
Regards D

The page appears to be down, you can check the google cache version and give him a call and see if he'll still make it. Other than that, it's basically a C channel with bolt holes for the T56 tail housing and two holes drilled to line up with the C-Beam. The ones from Pro-street haven't had the holes drilled in them for the c-beam so you have to mock it up for your car mark them and drill them.

One other things to consider with an '84 you'll have to go to a small nose starter to fit the LT-1 t-56 bellhousing. Again, not hard but something to remember.

I've been slowly doing mine over the last year (I wrench slow to say the least) but so far the biggest PITA have been the things that are normally a PITA with a clutch job. Specifically wrestling with the C-beam, wrestling with a 100 lb + transmission, cramming your fingers around the bellhousing, dealing with the lack of space in the corvette tunnel etc.

None of this is special to this swap and some of it is made easier by the opportunity to cut a hole in the middle of your car.
