I could not find a good example of this being done. Small block with 700R4, it is possible to install the whole blackheart system even though they say LS or anyone other than 700R4. The headers needed some work on the passenger side as the #2 tube crosses over the #4 plug. Driver side is golden but needed the I shaft pulled and some prying on the motor mount to drop in.
Crossmember required the 4L60 bracket and adjustable trans mount from summit, but fits the body great. UMI adjustable torque arm worked but needed the seatbelt bracket trimmed but might just be my setup.
The exhaust system took about 4h to install, only problem there was the hanger on the right side for V6 cars must be different, thankfully a local AutoZone had the correct one. Ground clearance looks to be better than stock, the trans pan would get wiped out before the exhaust got crushed.
This system was $$$$ but seems to be totally worth it, hope this helps someone, somewhere.
Nice work, was considering going this route myself. Got a part number for the summit trans mount? I'm guessing you had to dimple some tubes on the passenger side?

Yeah that's the one. Here's what it looks like on the ground, this is with umi lowering springs on the front and cargo coils in the back. The k-frame or floorboards will hit before the exhaust.
The fascia is just on there with a couple nuts to keep it off the ground, that's why it's wonky looking.
The only caveat and the linchpin for me, was the creative adaptation of the transmission crossmember adaptor bracket. It necessitated getting a B-body extension housing so the transmission mount can be relocated from the case to the extension. Which just so happens to be the transmission I ended getting through an error on the builders part (Corvette trans that also has different trans mount like the B-body).
My search for a solution is in the link below which at the time of writing was still unresolved. Not any more!
I've compiled a list of the various headers (1 3/4" and 1 5/8") as well as the complete exhaust systems (2 stainless grades for auto transmission).
The crossmember listed is for a 1984-1992 GM F-Body LS Swap T56/T56 Magnum/4L60-4L70*/4L80-4L85*/TH400*/2004R* Transmission.
All prices, descriptions and PN's through Summit. Holley's website isn't the most navigation friendly.
