I'm waiting to order a Holley pan, too. Been watching the date but I am seeing mid October, not November. Sorry I don't have another source.
I was watching their headers and saw them bump the price by $220 so I jumped on a set on eBay for the original price. But the seller couldn't locate the set he showed in stock so now I wait for a new shipment and watch the date move back a month each time the estimated ship date arrives.
I looked but I can't find what you settled on for headers and mounts. I did look up the TTI recommendations and they say you can run a z-bar but you have to modify it. If you are running the Holley mounts, the motor moves and the z-bar mount won't be in the right spot so you would need to build a new one of those. No idea on the Holley headers, they don't seem to make any comments probably because the stock trans/bell isn't in the factory location so it's kind of a "roll your own" deal if you use their parts.
So, I guess it depends on how much you want to build the parts to make the stock stuff work. Either way, looks like it requires some custom parts. Or you go hydraulic.
I know the bell will bolt to the motor, and assuming the flywheel is for a conversion, in theory from the face of the flywheel back it should be old school SB stuff so your factory stuff should work. Assuming you can get it hooked up.
Maybe that helps??
