Looks like a fork-lift to me!

Re: '46 Chevy Shorty

Sorry...I just couldn't resist that one --- Here is what it looks likes when not disguised in shrink wrap.


OMG!...I gotta stuff all that into what!?


Have to relocate the engine mounts to the aft position. There's just too much tranny hangin' out in back.


The trans wound up rotated maybe 2 degrees clockwise. Still not sure if I'll align the engine or the trans to the vertical.

Either way, there's a lot to get done.

Onward!

Re: '46 Chevy Shorty

Hey Tango, absolutely beautiful! I think I'd split the difference between the engine and tranny--that will make instalation a bit easier and the drive train won't know the diference.

Our trannies look very similar--huge. I wasn't certain if you were saying that there is no support at the end of the tranny and therefore you were moving the engine mounts back or if the move was on general principles. My motor/tranny mounts at the side of the engine and the rear of the tranny but there is nothing in front. Jack

Re: '46 Chevy Shorty

Hey Jack --- I've read numerous reports of issues with the front only mounting of 4BT's. Seems it puts the tranny in a bind since the weight wants to flex right at the engine/trans junction. And with such a long tranny I think I'll put my mounts at the rear, closer to the CG to help balance the load. Another 4BT trick is to set the engine mounts above the centerline of the crank. Supposedly, it makes quite a positive difference in how the vibes are transmitted to the frame.

There's a reason they call'em "paint shakers".

Re: '46 Chevy Shorty

Howdy Folks --- Thankfully, I swapped the good running 350 Chevy motor that was in it to a friend in return for assistance with cramming this behemoth into the bus. Best part is that he drafted his buddy to help who was a diesel mechanic for twenty years and has built about a dozen "Art Cars" from scratch. Personally, I'd be lost but these two should be able to handle just about anything.

As for "Flying"...probably not. For all that weight & mass, this Cummins is only 130hp. Should be plenty adequate, given that the original engine (straight six) was only 90hp and about 180 pounds of torque. The 4BT has 40 more horses (44% more) but at 355#''s of torque, double the grunt (50%). In fact quite a bit more than the Chevy V-8 I pulled out. I could easily pump it up to 250-300 horses but I'm going for mpg and durability. My target is "near 30mpg". We'll just have to wait and see how that works out, but if I can pull off even 25...with my 44gallon tank that would give me a range of 1100 miles on a tank. If I can manage the 30, that would be 1320. Either way, enough wiggle to hold out for the next cheap fuel stop.

As for the actual installation, I first need to find or build a rolling gantry. I have a feeling this package will probably have to go in & out more than a few times before it gets locked down. Craig's List, here I come.

Onward!

Re: '46 Chevy Shorty

30 MPG? If I got that kind of mileage out of my GMC van I'd feel like I'd died and gone to heaven!
