Here's the trans. A powerglide w/straight cuts and a pro brake. This is the biggest hold up in the project right now. I ordered a JW Ultra Bell for it 3 weeks ago and it was supposed to be delivered 2 weeks ago. Now I am told it won't ship until the 2nd week in January 
If anyone has a JW Ultra Bell for a glide to a small mopar or Gen III Hemi PLEASE let me know.
I went through the same deal with JW for a BB to pg bellhousing. I come to find out the old design had major issues and they were redesigning it. After some calling I decided on a much better solution with a mid-plate adapter from Coan.

The only problem was that this harness was not designed to work with the MAP sensor on a truck intake manifold. But who in their right mind would run a truck manifold on one of these anyway! I'll be swapping out to a car 5.7 intake and eventually a 6.1 intake. The MAP sensor wire will then work without issue.
I thought I had read somewhere that the truck intake was actually the best stock one for power. 
If the engine doesn't have MDS it will be pre 06 if it's a truck engine.

The 70 bee.. did they change over to the complete front end from a strut car? That would be interesting to see. I'm selling all my engines to build a gen 3 myself and will be watching!
You're not that far from me either.

you're going to want to turn that thing around, the usb port is on the other side.
i have perfected the efisource install.lol.
also if you're going to use the megasquirt to control your cooling fan,( highly recommended) you will want to run the fan wire through the harness before you get to far into your install. the efisource directions on the pin location are all the directions you will need.
i have an awesome tune up for anyone running eagle heads on an early engine with a decent camshaft too.

I will probably rotate it 90 degrees counterclockwise.

The 6.1 intake is by far the best stock intake for power.
If it is MDS I will be switching out those lifters when I swap the cam.

It is a complete swap - front and rear. If you need any detailed pics let me know and I'll snap some for you - as long as I can get them with the car on the dyno

It'll be interesting in seeing your dyno results between the 2 intakes. I dyno'd a 418 stroker using an 05 the truck intake and SRT8 6.1 intake. Even with the port mismatch both those intakes preformed almost identical to the point when I overlayed the 2 graphs I couldn't tell which was which.
That's interesting. Was there an aftermarket cam in the engine you tested? If so, what lift and duration?
What heads were on the engine? Since you mentioned port mismatch I am assuming old style 5.7 heads?

Yes, 5.7 heads. The cam was .578/.588 231/236 @ .050" 114+4
I'm going to blame the mismatched ports for the 6.1 intake as the reason you had the results you did.
The stock "old style" 5.7 heads flow a respectable amount of air and at a high velocity in comparison to what we are used to with the B/RB, Zeeker or Indy heads. However, with the availability and pricing of 6.1 heads plus the additional flow and direct match for the 6.1 and Drag Pack intake the old 5.7 heads are only worth their weight in aluminum. And with the reasonable cost of the Apache (6.4) heads the 6.1 heads are even becoming less valuable. And now with the availability of the Thitek heads (which I sell) for a few extra dollars you can have the best head currently available.
I don't know if my cable driven throttle body adapter will work with the truck intake. If it does I will test both the truck and car 5.7 intakes. I sold the adapter plates I had sitting here for years so I won't be putting the 6.1 intake on the 5.7 heads. I do have some 6.1 heads that I plan on swapping onto the 5.7. At that point I'll test the 6.1 intake (and maybe a Drag Pack if I can find a loaner or buy one cheap
Still waiting on my JW bell housing

For dyno purposes I gutted a throttle body so the blade was free to move then fabbed up a bracket to the blade gear for a throttle cable. Didn't look pretty, but was functional.

What vehicle or engine did that LS throttle body come off of?
Does it bolt right in or is an adapter needed?
Will that LS throttle body bolt on to a 6.1 manifold?

I know that fast has a hemi to lsx Tb adapter plate. You can use any FAST style or Nick Williams cable drive throttle body.
I've got a BBK hemi Specific 80mm 1791 on my 6.1 intake.

The TB is off of an LS1 vehicle. It will not bolt directly to any Gen 3 Hemi manifold. It does require an adapter plate. I have several "prototype" adapter plates that I have tested and will be using one of those. There is also a company making direct bolt on cable driven throttle bodies that I will be selling once I test and verify functionality.
