The muffler shop can always install a couple Magna Flow universal catalytic converters if you are in an emission state . This hobby just keeps getting more expensive when ever you change a major component
I'm in a county in NC that doesn't have emissions. Only safety.But with it being so old it's exempt from even that. I just don't want to run cats and some of them fuss about running non original equipment these days.
That's the problem when one moves a 1000 miles away and don't have friends with shops anymore.I'll take a look at the bow tie cross member and get under the car. Maybe I can get by with the existing exhaust.
I did this swap on a 1978 Trans Am 25 years ago. Re drilled the stock crossmember and used that.
Maybe it's possible to do that with this?
Try to find a pre-80 stock crossmember (with the two holes). The trans mount is removeable. SST sells one for the TKX. Perhaps it gives you the room you need.

my Bowtie crossmember just got to my house today and im on my way back home from vacation, I would be happy to take pics and measurements
I have 2000 stall converter on my RamJet 350 equipped 200-4R. I have 4.11s in the rear and plenty of torque and it feels just fine to me. I'm not a racer and I just cruise around and it works for me.
I modified my crossmember to make the exhaust "pass- under" when I put in the 200-4R. The path just seemed overly tortuous to have it snake around the 200-4R while using the stock exhaust holes in the original crossmember. I just recently fabricated my own crossmember using 3" by 3" boxed steel. You can eyeball that in the attached link. Not sure it was worth the effort but it was entertaining. I actually called Bowtie Overdrives to ask about their auto tranny crossmember but they didn't have any that day (I was going to modify the ends to fit it into my manual "stubs"); so anyway, I just started working on fabricating my own. https://www.corvetteforum.com/forums...an-gasket.html

I have been consistently told that I may get a little frustrated with the 2600 stall for normal driving with my set up as well as generate more heat and don't want that here in AZ.
the th350 and 2004R are about 2-3 millimeters difference in length (except long shaft th350) and the only difference is mounting location is several inches further back on the 2004R... I have a crossmember coming from Bowtie Overdrives, I have the new TV cable and bracket as well so gonna tackle it when I return from vacation.
I'm planning on using current lines with a little manipulation
Mine were cut and swapped to rubber with clamps before I bought it, I purchased a set of aero-quip style lines but I'm not sure how I feel about them, might just flare and make new ones from Ni-Cu.
How far back does the crossmember have to be moved for the 2004r install in place of a TH350?
it doesn't have to move back at all, for 1979 and older the th350 mount bracket needs to be removed from the crossmemeber and the 2004r will bolt right to it, for 80/81 I needed to purchase a new crossmemeber from bowtie overdrive because the th350 mount is welded to the crossmemeber.
I've got mine in the car, bolted to the rebuilt engine..
I did notice the drivers side exhaust needs to be reworked because the pan fits significantly different, but I've sent photos to my exhaust guy.
I am running AN -6 line from the cooler lines to a separate cooler, I changed my plans of using solid line, as it's a pain to re-route everything.
The trans cross member (1978) was simple enough, got it close, drilled a 1/2" hole with a uni-bit and it popped right in. Aside from that, everything else has fit in easily, even the same damn speedo cable port, and I did not need a new yoke.
Total time for work.. Dropping in engine took 12 minutes, but I've got an electric chain hoist.
Putting in the transmission.. 1 hour and a fat lip.. Four guys, and a two post hoist.
I would never attempt this on the floor, thank god my divorce paid for my 2 post, and transmission jack.
Using AN -6 for your cooler lines is the best way, 1/4" NPT to -6 male fittings, and then two 90* elbows lands you between the header and the starter, well clear of the heat.
The stock GNX dip stick tube fits with minor modification, it was very close to the stock TH350 shape.
You'll need this for your TV cable if you've got a quadrabog, my cruise control bracket where the original TH350 TV cable was attached was set too far back, and wouldn't allow proper movement.
This is an easy swap, no modification to my exhaust, crossmember fit, very easy in a 78.
Just commenting for future reference in case somebody is looking for info. It is 1/4" NPSM (*NOT* NPT)..... use NPSM, last thing you want happening is cracking your tranny case.
With minimal room on my 68 manual tranny tunnel these SHORT 1/4" NPSM to 6 AN banjo fittings worked great..... I bought 4 just to check how they were built.
