New Hooker 73-87 GM truck LS swap system preview
#243
I unfortunately can't say one way or the other as I don't test fit the Hooker headers with anything other than the mounting components I design them to be compatible with. I've also not read any anecdotal evidence of them fitting or not with any other type of mounts, although I'm sure there's guys that have used them with mounts I'm not aware of.

They may bolt-on to the engine, but they lack some features that come with the newer Squarebody specific headers, such as: they are not compatible with the stock LS large boot spark plug wires or 4L80 transmissions, they don't have flat finished TIG welded flanges, they don't have formed-merge collectors and I don't believe they will tuck up above the bottom of the frame rails.

I've not posted any new information in this thread in a while and thought I'd share some new Holley accessory drive options that apply to this application.
Holley has recently released a new accessory drive system that shares the same component configuration as the 4th-gen F-body FEAD. This set-up is capable of being installed at both the F-body and truck offsets with the parts contained in the packaging; installation at the Corvette-offset is not possible.
A very cool feature of this set-up is it allows the user to install the small or large truck type alternators as you can see in the attached photos.
The new Holley low-mount A/C compressor bracket for the Sanden SD7B10 also shown in the photos has the capability of being installed at the Corvette, F-body or truck offsets, depending on the vehicle application and the specific engine swap brackets being used.
For those of you using the Hooker 12612HKR 73-87 GM truck brackets, the A/C compressor bracket can be installed at the F-body and truck offsets without have to cut or modify anything.
The parts shown in the photos were painted black by the vehicle owner and are not available from Holley in that finish; all production components are bare aluminum.

This whole swap is very clean looking. That is how I see my build looking, using Holley valve covers and fuel rails. But not ACC drive.

I wish it could've worked out for your project also. Unfortunately, we have to deal with the constraints imposed on us by the design of the vehicles we work on and the steering box location in the 64-67 A-bodies severely limits accessory drive choices. Are you still looking at the Wegner set-up?

I know you can keep the dual tanks. A Walbro 450 intank pump will work well in the '87 tanks since those have a FI from the factory and have the baffle for the pump already in the tank. I have seen the other parts, but I will have to look that up...

for the selector valve you need to find a Pollak 42-159 or 42-159S. These are high pressure selector valves rated to 65 psi. Both have a 3/8" supply line and a 5/16 return line.
Here is an install sheet for them...
http://products.pollakaftermarket.com/Asset/IS-41_b.pdf
Here it is:
the '87 uses the same tank on both sides, your existing filler necks and mounts will work. Use Spectra Premium GM11C fuel tank.:
the '87 sending units:
Driver side: Passenger side:
Its straight forward after that, easy set up if you are running the return style rails on the engine. If you are running the returnless style, you would need to mount the filter/regulator in the system. I have never done that, so not sure where to put it....

RSJ78, I'm posting this photo for you so you can use it as a reference to judge the clearance and position of your 4L60 trans and your floor. Dose the step in your floor appear to be in the same proximity to the extension housing flange/bolts on your trans as it does here in this photo?
