Moving forward

So here it is in place:

and here are some of the transmission cross member you can probably see some of my concers:

^ with the camera prependicular to the yoke face of the front axle.

^ and from the just behind.

You can see the clearance was just barely there. Well the spacer I had in there between the stock crossmember (moved back about 2") and the transmission was a 2" x 3" .120 wall box tube. So I put in a 2" x 4" and picked up more. But there is only +/- .5" between the upper most parts of the TCase and the floor pan.

The extra inch also helped reduce the dirve shaft angles:

^ this was with the 3" spacer in.

Plus I ground down the rivets and removed on the upper TCase xmember seen on this photo:


So that's the up date. Next, fire the engine! I have never heard it run and it makes me a little nervous. Brakes: The MC and Hydroboost are from a 86 military truck and the ports are BEASTLY. plus I need to figure out where to plumb in a preassure reducing/ proportioning valve. And the Clutch.. Russell makes a fitting to convert the factory master/slave fittings to AN fittings. Very nice pieces.

Re: 6.2/6.5 into a 4wd?

Its been awhile, collecting parts and cementing directions. I mostly have the cooling done, the rad is set, the shroud ordered, I have almost settled on a fan (HMMWV mechanical) and a thermal clutch. The rear driveshaft is ordered, received and its a beautiful Tom Woods piece (highly recommended). Turbo, interior, gauges, exhaust, wiring that's about it. Its getting closer...

For anyone who has ever wondered how dificult it is to put turbo 6.2/6.5td in a 4x4 67-72 truck, check out these clearances:

^As you can see, clearances are tight, the injectors are still the 6.2 long style and they contact. The exhaust manifold contacts the frame at the 3rd port back due to a casting knob and the back slide of the flange is ~3" from the factory box.

And here's what is hopefully will sit on that manifold. Its hopefully going to be a VGT Holset w/ and electronic controller.:


I installed a TPS and Cam sensor (RPM) so the goal is to do an electronic controller (NOT CAN controlled) that will set a boost target from a table of these 2 values. If anyone has recommendations for a shallow EGT and exhaust pressure sensor I'd appreciate it.
