"The Holley accessory drive set-up fit real well with the Delphi 600 PS box using the Hooker forward-bias engine brackets..."
I am using the Holley accessory drive on my 65 Skylark and it fits and works just fine. Plenty of clearance. I have the 1995 Jeep Grand Cherokee steering box.
Thanks for adding your experience of fitment to the list.
How does the accessory drive fit without the truck spacers? With the vette and body spacing.
No problem at any spacing when used with the forward bias Hooker engine bracket set; I have yet to test fit the various accessory drives with the rear-bias brackets, so the fitment report in that instance is still pending.
Long-tube header prototyping was completed today, which means exhaust system prototyping will begin on Monday. The headers will fit equally well with the Hooker forward bias or rear-bias engine mounting brackets and the starter will be serviceable without having to mess with the passenger side header assembly.
Do you think there will be interference with the later collapsible steering column?
It will probably depend on whether the car in question is a Chevelle, GTO/Lemans, Skylark or 442...there is noticeably more clearance between the driver side header and the shaft in our 67 Chevelle than there is in the GTO shown in these last photos. This would help to explain why I've noticed multiple complaints regarding header/steering shaft interference with a couple of different existing headers on the market. If those headers were prototyped on a Chevelle and never validated for fitment in a Pontiac version A-body frame, then the tighter clearance would never be discovered to exist.
That quick. You guys don't waste any time from prototype to the shelf.
That time frame is for the rollout to begin...the engine brackets and long-tube headers will show up on the shelf first, followed by the transmission crossmember, and then the exhaust systems.
Will the long tubes go in from the bottom? What is the performance difference in the long tubes versus the cast iron headers. ? Those cast irons look pretty sweet. Nice view from the bottom too. Gotta love a good clean frame!

Yes, the headers will install from the bottom. You'll have to remove the starter, engine oil dipstick/tube and spark plugs/wires to accomplish the task. Depending on your particular engine build, the long-tube headers could be worth an additional 15-30HP over the cast iron manifolds.
Since you are using a chevelle frame, will this also bolt directly to a 67 olds cutlass frame? I am researching what I need and will be following this. Thanks

I am hopefully optimistic that the frame rail adapters for the crossmember will be compatible with the Oldmobile application frames, but I can't say for sure until I have the opportunity to validate that their crossmember attachment hole pattern is the same. Can you confirm for me at least that the pattern in your frame consists of 8-holes per side (maybe more if someone has done a trans swap)?
I have a conv. so my crossmember is bolted to a adapter(?) welded to the inside of the frame. On the frame itself outside of the adapter there are 8 holes per side.
