Dr Jay nice timing, I will be installing a MAF TPI with the 165 computer in my 77 next month. What will you do for fresh/filtered air forward of the MAF? I believe the MAF uses a 2 pulse VSS.

I've seen the oblong cone filter squeezed in before...it seems to work well on cars with electric fans.

I promise to post pics.
The speed sensor is a minor problem, but I think I have the wiring figured out. I'm waiting for any other forum members with experiance to chime in on it. Otherwise I,m going to ground one wire, and the other wire I will attach to brown wire at pin-out A10.
Do you have any suggestions, tips, hints? Any thing is useful.
I'm doing this as a "If I put my mind to it I can do anything project"
I can advise that if using older heads with the TPI when you elongate the 4 center bolt holes a die grinder with a 1/4" drill bit works great to mill the aluminum. Take a little off at a time, and test fit the intake for alignment frequently.
Do you have a custom prom yet? I used these guys, they were very helpful on the phone with my questions.

about your VSS wiring...
take a look at this website....
it has a simplified wiring diagram of what I believe you're looking for (down towards the bottom).

I see a lot of the sensors are alike...but does any of that info from that link pertain to an LT1 EFI system?

Nice install!
You can buy a spark plug anti-fouler and cut it short to make an inexpensive O2 bung. F-body accel cable should work, but it's a little long. That's what I used in my truck. In the Vette, I used a 91 C4 cable. The inner cable was too long and I had to use a hood cable stop to get the correct pull. In another TPI swap in a 71 pickup, I used an 88 TBI pickup cable and it was a nice length.

I'll try the F-body throttle cable I can deal with it being al little long. Thanks for the advice. Any thing else you can recomend is appreciated.

Durango, the only part that I don't have yet is the air cleaner element.
I now just need some more free time (rain day at work). I got the fuel lines to the rail, and filter plumbed last night (sorry battery was dead in the camera). This evening I plan on starting to install the wire harness.
If everything goes really well I hope to have it running on new years day. I'm crossing my fingers.

I was fooling around with the fresh air intake last year on my old 350, that was prior to installing the new 383, I went to the wrecking yard and got several different rubber elbow's from various cars, I even bought a stock C5 assembly off Ebay, seemed like everything that I got to work looked "REAL" bubba, this was because I only had 3 inches play with from the MAF to my radiator, I wanted to do better than this. What I wanted was fresh cool air forward of the radiator but I don't want to cut up my radiator support to make room for ducting, I also was trying to hook it up to a stock type filter housing, that was so I could run to any parts store to change my filter, I gave it a break and figured I'd get back to it this year.
Well I'm back looking at it and I've also talked to a few competent friends. What I am planning to do is build and attach a U shaped shield to my front frame crossover, this is to house a standard aftermarket round/cone type filter and hopefully keep alot of turbulence down, I know I'll be getting warm/hot air from the engine compartment but I'll take that trade, I will just have to plumb a 90 deg down from the MAF and then to the box.
I am also very open to ideas
