whats your next move?

Are you asking what I have to do next? Or was this mean for Adam? :laugh:

I have to do the harness bar and the X brace behind the cab. Then pull off what I can, fully weld the cage, paint what I can, drop it back down on the MJ and weld/paint some more.

Once that is completed (hopefully this coming weekend) I'll start pulling the current drivetrain. I have the two D20s I have sold (have to ship them to someone in WV) and I'm just going to wrap/store the 4.0/NP435 until they sell.

Then I'll get a mock-up 440 block/heads/headers/etc. throw into the engine bay along with the rest of the drivetrain and start mocking everything up and building engine mounts/new crossmember/bellypan, etc.

BLUE?!?!

a mopar guy like you, and you painted the block, blue. wheres the orange.

son, i am disappoint.

That is actually GM blue. Looks almost exactly like it. I rebuilt a 400 sm block (truck motor) for a 4WD El Camino I built many moons ago, and painted it that color.

I cannot wait to see how this thing runs Colin. Are you adapting fuel injection to it, or modding a carb to handle trail abuse?

My uncle said it might be closer to Ford blue :laugh:

I'm pretty much settled on losing the carburetor (only using one for break-in). I've yet to see one in person that worked well on the trail. Just hearsay on the internet.

The route I've chosen now is to run 3 TBI throttle bodies controlled by Megasquirt on a six-pack manifold. Linkage will be one to one, with all the injectors just daisy chained together and only use sensors on one throttle body. Should provide plenty of air/fuel as well as being scalable to any upgrades I want down the road (cough aluminum heads cough) :D

LOL... yeah, the Ford blue color is very close to the GM color too.

Sounds like a good way to control fuel. I would put sensors on each TB though, and be able to switch the wiring from one TB to the other for troubleshooting/dialing it in. Also, keep in mind that you will create more of an amp draw on the injector source (from the megasquirt) make sure that the megasquirt can handle the amp draw of having 3 injectors daisy chained (I am guessing that it typically only drives one injector). Some of those systems are very finicky with voltage/amp draw.

I hope it works. My experience with multi-carbs has been that it looks cool.... but is a pain in the arse to keep it dialed in. I never messed with multi TB's though, hopefully they are not as susceptible to climate changes.

I've never worked with MS before, however my friend has done a couple projects with it. As far as I know, it can handle multiple injectors but not necessarily daisy chained together. I have to figure all of that out.

Haha, hopefully it shouldn't be too hard to keep dialed in. My main problem is stock throttle bodies don't flow too well. The cheapest aftermarket system I've seen out there though is on the order of $1,800 and limits you to ~500HP. I should be under $1000 by the time I'm done with the potential to run any power I want.
 
I would have to agree on andy's comment about injectors. Are you putting the MS together yourself? It sould be easier to swap in a beefier driver transistor while assembling it, or even just duplicate the driver circuit 3x and tie them all to the same logic level signal. Got a link to the particular MS setup you're using? I'm not too familiar with them.
 
Looks great but I can't help but laugh looking at that enclosure and the db series connectors.

You are gonna get that poor thing covered in gunk so fast :laugh2: I'd suggest a good waterproof enclosure and automotive grade connectors.

If you end up needing a hand with it let me know. I've got all the scopes and whatnot in storage just itching to be used.
 
Mad triangles.

Bill this is what I was trying to ask you about.
