There are a few things to consider and I have a call tonight at 5:30 to discuss the destiny of the manifold. Push come shove, the tooling may be for sale, I may take it over solely and oversee everything or maybe never to be produced again which would be worse case. Who knows how this call will turn out?

I hope for the best and the Renegade manifold can stay in production. I really think you did the crossfire owners a huge benefit in performance with that intake and there is no substitute for it. The market for a replacement crossfire intake may not be very profitable but I think that if was packaged with a stand alone controller, injectors and maybe even electric fuel pump as full system it should increase it's market for the sbc. And have good hood clearance also.
Good luck Buck.
Good luck Buck.

When I bought my 84 the first thing I did was source a Renegade because I was worried that they would soon go out of production. There were over 50,000 84 corvette made, not to mention the 82s and all the F bodies so there are plenty of crossfires out there struggling to breathe. The only problem is these cars are relatively cheep so not everyone will spend money on them.
What would be handy is a published list with expected performance gains for some of the standard upgrades. These could be supplied by customers, there are enough guys here who have used the Renegade with new heads, cam, injectors and ECM. The data could be gathered and normalized ie if you make these changes expect gains in this region.
Anyway that’s my “two bobs” worth, I really hope Tom can keep that intake in production it gives crossfire owners the option for genuine performance gains for limited cost and limited effort.

It all comes down to cost. I was also thinking about something to do with the top plate to show it was a "blue printed" manifold, but I need to work on that one. Also have some other things in the works to do with the manifold that I talked with my machinist about and is on-board with. Who knows what might pop-up and become available in the future? 
watch the forum and the site for more on all this as it unfolds. Thanks guys!

So, we ARE going to pull the tooling, but Jim is going out of town so we have to wait until he gets back so we can both go to CA to inspect everything and see what is going on. Hope to setup something with the foundry there before leaving if possible. Keep your fingers crossed that the tooling is not damaged and I can proceed with the project.

I decided, based on quality issues, to return my Renegade. It was a sad thing to do, but I feel the quality is more important. I did pick up a cheap 5.3 complete with the swap intent, however, in light of recent developments, my option for a quality machined Renegade remains open! Keep me informed, please.

I think that sounds like a good call.
I had some pretty bad casting issues on my renegade.
There was a solid wall in the runners thst went over the egr passage.
i think if i just straight installed vs reworking the runners, i would had some running/tuning issues.
i also installed my renegade with a mild camshaft, new heads, long tube headers, and exhaust system.
It had tons more power with the stock computer/tune, and for the first time ever, a powerband!
i did end up needing to go with an ebl flash to get it running right, and to get some driveability issues fixed.
that old cfi can surprise people now.
cocky kids and their imports hold their heads in shame when beaten by an early C4.

Maybe I missed it, but what kind of improvements could you expect out of an “internally” stock CFI car with the Renegade and typical mods (cat-back, bump fuel pressure, ect)? I could see a huge improvement for those with 383’s or 350’s with a bump in compression, ect.

You should see on average on a stock 350 CFI motor a 32HP increase to the rear, depending on the condition of the motor, you can see even a little more. It really likes to be on a modded 350 or 383 and larger.

I recently found out that it can be port matched to a 1206 intake gasket... with that said I don't think the intake is a restriction one even a hot engine... I think the issues arise in the throttlebodies themselves. It really is nice.

I'd add that the TB's aren't a restriction until you are well over stock power/displacement. CFI-EFI and I both bored our TB's and saw zero difference at the track. His was a ported intake/exhaust stock engine, mine was a mile (~300hp) SB400. I think the swirl plates are a restriction long before the TB's are.
