Post Scrapped the 6.2 for a 4BT

I don't post much on this site, I'm more of a 'lurking' type. I figure its time to post the M715 project. I've been running a 406 Chevy with TH350 trans for a few years. I decided to build a 6.2 Turbo diesel and SM465 trans.

Before disassembly



Test Fitting





Motor plates made by Tom Lawlor aka 'Spicergear' from the M715 zone.





Fan/water pump clearance



Hydroboost





A few minor adjustments and I should be in good shape.

Now its time to make the rest of the truck look better.

I LOVE the army look. That is so totally cool. Nice work on the motor. You gave me some ideas for mounting my 455. Now, where did you get that awesome fan?

Edit: boy, when you post, you don't play around.

The engine is no where near running yet. I originally was going to run the 6.5 turbo set up but the turbo manifold does not fit the 6.2 heads due to injector clearance issues. Custom headers will be made. I'm going to run a Holset turbo off a Cummins.

The pictures are just for mock up purposes. Once that is complete, th whole truck is going to the media blaster.....I'll probably get the remains of it in an urn

Bringing this thread back from the dead. I haven't been on the forum in a while, and haven't touched the truck for the past year or so.

The truck hasn't changed much in the last two years, but the direction has changed. I took a very much needed welding class. Scrapped the 6.2 diesel for a 4BT. The 4BT sort of fell into my possession in January, so I fabbed up the motor mounts, trans and t.case crossmembers, removed and rewelded the spring perches on the 14 bolt/ Dana 60 axles(since my first attempt was more boogers than weld).

2 years ago the chassis was media blasted, then I brought it home, prepped it with phosphuric acid, and painted it with POR15, then primed it, then 'drabbed it. For some reason the frame pitted/rusted under the paint, so it was back to the blaster last month before final assembly.


Here she is. Sorry for the large pics.


4BT test fit in the pitted frame.






With the 'drab applied











It feels good to be working on it again. I really miss driving this truck.

WOW!
Very Nice!

Question: In the earlier pics, what is all the sheet metal dings and wrinkles in the firewall?

I love the grenade shifter knob!

The previous owner did some clearance work with a hammer. I fixed it with Herculiner and insulation

AWESOME!!! That 4bt looks right at home in there. Almost looks small in that engine bay lol. The shifter knob is a nice touch too. Can't wait to see this thing finished!

shifter grenade rocks (I'll be borrowing that idea!)

Btw, did you have the rig dipped in paint? Looks too even to be sprayed (j/k)!!! Awesome rig

My paint job rocks! I made sure that there was excessive dust and debris in my garage prior to painting. I even managed to get a fly painted into the hood. It will be a beautiful truck....in a hard working, daily driven, abused, trail driven sort of way. I am really happy with the color. I was a little scared at first, cause it looks nasty in the paint cans. 2 gallons of WWI light green flat/1 gallon of stock Vietnam era dark green semi/ and 1 gallon of Korean flat. Mix it all together and you get perfection.

Anywho, when I get some more time I will write up all of the details of the Cummins swap and all of the part numbers involved for a GM NV4500. There are a lot of little details that I am learning along the way.

I love the OD green and the Mich XL's. Could you post some pics of how you did your motor mounts for the 4BT. I'm at that point right now with my swap. From the looks of it your using a chevy bell and tranny. Thanks!

Man when I see this it makes me what to put my 4BT in my 73' J-4000......

I'll get some pics of the mounts up. Mine are ugly, I quite literally made them in about 15 minutes. 3/8" x 6" angle iron hanging off the frame rails, same thing off the front of the engine in upside down 'L' position with a Dodge 5.9 insulator sammiched in there. Of course, I gusseted the angle iron. I also installed the engine with the 8* tilt toward the pass side.



Some pics of today's work. Front fenders installed.
