It's fairly close. There's a couple extra inches in the front, which I'm just going to bury into a bumper. There might be 6" more in the back, if that, it measures about 8' 4" from the back of the cab to the end of the frame. The rear axle isn't in the same position though, it's farther back. This frame was from and extended cab short box, so it's a 138.7" wheelbase, I think a normal long box J truck is 132". The regular cab long box second gen is 134.7", which is a pretty close match.

I'm just going to throw some sort of flatdeck or logger box on it, so it doesn't matter that the rear axle isn't where it normally would be.

Engine is hanging there with the NV4500 bolted to it. It does fit.

I have other stuff to post, and questions, but that's for tomorrow.

What's interesting is that the GM NV4500 feet basically line up with the Dodge trans mount... But it needs to be about 5" higher.

Image


Firewall clearance is tight on the passenger side, and there is no way the factory heater core setup will work. I think I will buy a Mojave heater.

Image


Steering clears, driver's side manifold clears fine.

Image


Lots of clearance on the driver's side firewall.

Image


I also had the whole front clip on and reasonably lined up, so I could build the core support/front body mounts.

Image

Image

This mount will get changed a bit to make it stronger.

Image

I might actually box in the inner side of both of those mounts, just to fully discourage them from tearing off the frame.



Questions I have (and will look for the answers for)

-Will the stock sized radiator for my 78 front clip cool the 5.3 decently? Is there a common upgrade radiator I can order? I don't have the original rad anyways.
-Is an XJ steering column the best bet for a swap? I think I just need to cut the firewall mount flange off and weld it in a different position? The column and wheel I have are screwed. There is a newer column in the orange cab, but it needs a lock cylinder at least.

Boring pictures. But there is motor mounts hard tacked in place and holding the motor.

Image

Image

I will pull the motor back out and weld them up more and add some other bracing, but I want to tackle the trans mount first, and maybe steering column and brake booster setup. Plus I have to swap a 4L in a J10 tomorrow for a friend, so I just needed the engine in and out of the way for the time being.

Also, forgot to ask... Is there covers available for the lower part of the bellhousing when using a NV4500 with a LSx? Must be?

Any reason I shouldn't buy this radiator? http://www.rockauto.com/en/moreinfo.php ... 75&jsn=836

Using the rule of thumb it should be big enough to sorta adequately cool the engine.

Is there a common upgrade radiator to use?

Oof, $810 Canadian, not including shipping.

Or for almost $600 Canadian, I could buy this plastic POS from Omix that probably wouldn't fit and would blow one of the tanks off within a week. :lol: :lol: :lol: :lol: https://www.summitracing.com/int/parts/ ... /make/jeep

Google it, summit is too proud, could probably get one cheaper off ebay.

It's hard being in Canada. Most people won't ship or screw you on it. Summit is reliable to deal with.

I'm going to look for a generic most likely, since I can go thicker and taller... There has to be something with more core capacity. That Griffin is the biggest of the FSJ specific ones I found, but it's still only about 3/4 the core capacity of the OEM GM rad.

So, sorta progress, er, ish.

Stock Dodge tranny crossmember...
Image

I spent a bunch of time looking at it, and hating its stamped metal formification, and how screwed up Dodge made removing it. The sides aren't straight, they taper, it wedges itself into the frame. I'm guessing this is actually a fairly legit design in regards to ease of assembly at the factory, and overall toughness in service, along with low cost. But it hung down way farther than it needed to, and just wasn't suitable for modification. So I tossed it.

Took a piece of 2x2x.188 HSS and threw some 1/2" XHS sleeves into/onto it:
Image

Pretty weld thread? Nope. But they're not gonna fall out.
Image

And then after much fiddling around I got this all tacked up.
Image

That way the crossmember can actually be dropped, rather than having to go UP to get out (like Dodge intended). Dodge did nothing to make this easier, the area on the frame it bolts to isn't even flat, so I had to stack up/weld together pieces of flat bar just to get it to sit correct. Am I totally happy with this? No, not really, but I bet it will be fine.

It all has to come back out for final welding/cleanup and a few more braces pieces on where the actual mount attached to the crossmember.

Then I wanted to figure out seats, and the brake booster, and such. Which meant putting the steering column I actually intend to use in.

Image

Guess what? An XJ column doesn't fit the 66 dash. I probably should have known that. Hell, I'm probably the only person here that didn't know that. So, the tossup now is if I should swap my 73 dash in, or cut the 66 dash. I'm leaning towards cutting the 66 dash, as I'd rather keep 'more' of the original parts and character of the truck, since I'm using precious little as is. Plus my 73 dash isn't in great shape anyways. Comments?

Also, I ruined that XJ column because I cut it the wrong way. Yay me. Cut the flange off where it bulges out, not at the weld. Luckily that column was a freebie that was out in the shed and didn't have the steering wheel I wanted, but now I'm actually going to have to go buy a column. IF I can find one, pre-96 XJs are actually getting harder to find, being something of an early XJ/MJ fan myself.

Trans crossmember is all welded up.

Image

Still not totally sold on it being the most awesome thing in the world, but it's holding the tranny in place right now, so that's a success...
