Had a shed built so I could put all my junk in it and mate the engine and transmission together when I come back in December.
Spent the few days I had off doing family stuff mainly.
Links and other small things
Moved the engines transmissions and such into the shed
The brown lipe aux transmission
It's small but strong(and freaking heavy)
Preview of coming attractions: Once again small, strong, but this part is not so heavy despite lots of beef.

I was planning on using the orange 350 for 30k or so while I saved up for a crate engine that would give 400 lbs torque as low as I could get in the rpm range.
But, then I seen this and JUMPED on it.
It is a 68 472 (with 72k) putting out 500lbs just under 2300 rpm which is perfect for the ratios I plan on running. Due to the nickel content it's lighter then a 454 and if I install a aluminum intake it is only 50 pounds heavier then a sbc.
Here is the heavy intake
The engine also came with the 68 th400. I am going to see if my dad can use it on his Buick. If not I will just hang onto it and use it later.
Back at the house and checking measurements again to make sure everything will work. This dang thing is going to add 5" to my wheelbase but it should be totally worth it.
Pulled out the brownie and weighed it out of curiosity.
Double checking the layout. Everything still works out exactly as planned.
This is the measurement from the fan clutch to the flywheel.
First propeller shaft trans to brownie 7" shaft
Then another 7" shaft from the brownie to a box I had representing the transfer case
For a total length of 8' from the fan to the front of the transfer case.
I know this is long as heck but it is super long because I want to be able to work on the engine easily, replace the clutch easily, and if I decide to switch to a different transmission later (or swap out the brownie for a divorced klune box) I will have a lot of room to play with.
Began mocking up the shifter location. Everything will work out exactly as planned with plenty or room for skid plates under the motor and transmissions.
I will need to make a slightly longer main shifter to keep from hitting my elbow on the back of the cab. But the brownie shifter is perfect right here and easily within reach without being in the way of the steering wheel.
That is all I managed to do today. Doing family stuff tomorrow and should be able to start welding on the cab once again the 24th(weather permitting) and begin putting these measurements to good use.
I wanted to run the 472 before I left. But, it needs a oil pump which is special order no matter who I tried. The caddy to Chevy bell housing adapter is all special order as well as most of any performance parts. I need to run a relocated oil filter anyway so maybe I can find a pump that would make that easier.
I don't see any need to mess with this engine internally. Upgrade to hei and a lighter "stockish" intake and go is the plan. In stock form it will be reliable as all heck. The high compression will love the propane (without any mods). I will upgrade the water pump and other small parts to make it more reliable as they go out or when I simply get bored.

Spent today cutting, notching, and grinding. Lots of prep work measuring the new motor, cage, back to the motor, check the cage, etc. Also had to move a few things around in the shed to notch in there as the shop was being used to paint a car.
Shed looks a lot better.
Lots and lots of tubing all prepped and ready to be welded tomorrow morning.
I have all the edges grinded down and the mating surfaces on the cage all grinded down it was just to dark to take a picture.
Everything is all good to go and set out I am just waiting for daylight

Began welding this morning at 7am. It was a bit cold but not bad my mask kept fogging up though. I only had 3 hours to play with before I needed to do another family thing.
I welded up the back tubes, the six side tubes, and the front cross bar. I also fully welded up the bottom and cleaned it up.
It is hard to see in this camera phone picture but there is a 1/8 gap between the all the door pipes and upright. I plan on welding a gusset to the upright and tube to support it further once I get some plate steel.
The 1/8 gap is so the doors can slide inside the tubes without actually grinding against the rear upright.
Here is the doors they slide back to open and close. I only had the 3 pieces of balsa but you get the idea. There will be 5 total arms to the doors welded to one upright when finished to give side protection as well as stiffen the entire cage.
Here are the rear slip tubes. I only mocked them up because I did not have enough time to weld the 1.5" bracing from the bottom corners and bottom tube. The entire motor and bell housing sit under these tubes. This will make changing the clutch very easy. The rear watts link welds to them as well as rear suspension mounts. The axle tube sits directly behind these tubes. The crank pulley is only 4" away from the axle tube. The front has the same basic setup but is shorter.
I picked up all my junk and had a bit of extra time left over so I sat in the cab and checked the "mock up" seating setup.
Lots of leg room for the hanging pedals
Future grab handle location within easy reach
Good amount of clearance between the steering wheel and "door".
Good visibility to the left
Good visibility to the right
Over left shoulder
Over right shoulder
And over the dash
I was not 100% sure until I actually sat down but window bar is also the perfect height for comfy arm resting (once I side out the lexan that is).
That is as far as I could get this time. I will be ordering parts to mate the 465 to the 472 here over the next month through MTS(500cid.com). I hope to have the slip tubes front and rear welded up next time to get a bit closer to fitting this engine and transmission inside the cab.

I'm curious what the overall height will be once it is on a suspension/tires, etc...

Kind of looks like a tube version of a semi truck cab.

Glad to see you get started on it! What "look" are you going for? If I were you I would quit welding and start tacking. You will change stuff as yoy go and it is a hell of a lot easier to cut tacks than welds!
