Not sure weather to report or thank you. Lets go with thanks!
Really nice of you to put that together!

We have the prototype process underway for the ancillary items.
Shown is the LHD setup for the PS Pump, AC compressor, and alternator.
The RHD was completed a few months ago.
Get a few hrs here and a few hrs there to work on these new projects, often when you should be sleeping.

292 kit updates:
Adapter castings are due out of the foundry on 7/19.
Mounts for the PS pump, alternator, and AC compressor have been prototyped and will go to production ASAP.
Metal motor mounts for the engine to 4 cylinder frame are being produced.
Metal mounts for engine to V8 frame are going to production as soon as the 4 cylinder mounts are finished.

Hoping to have kits available in August.
No prices yet.
First production run will be 6 LHD and 6 RHD kits with or without AC for the 292.

Kits do not include an engine, but if you need an engine we could likely source one.
There is a local rebuilder that will completely remanufacture a 292 for $1,700.

Next we'll prototype the motor mounts and ancillary mounts for the 230 and 250 engines.

For those of you that have not read the entire thread, the kits will allow you to bolt a Chevy 292 inline 6 cylinder engine into a pre 300TDI Defender or V8 defender without any cutting or welding.
No changes to frame mounts, driveshafts, transmission, gauges, and so on.
We did an engine swap in a weekend.

Adapters castings shipping from foundry on Monday, 7/22/19.
They need to be machined into a finished product.
Those of you on the waiting list for kits should locate an engine if you haven't done so already.

Fresh from the foundry.
Picked up the adapter castings, loaded them in the back of the 110, and dropped them off at the machine shop.

Here's what the engine adapter looks like after they have been machined.
This was an adapter from the last batch that was produced for our series conversions more than a decade ago.
This adapter goes between the Chevy engine and the R380 Stumpy or LT77.

Just ordered the P/S Pump Pressure Valve Shim 899001 Kit from Borgeson to reduce the 1,200 LB Saignaw pressure down to 800 for the Land Rover steering box.
Looks like an easy install.
Can be purchased direct from Borgeson or from Summit other vendors.

Installed the shims in the Saignaw PS pump mentioned in post 353.
Removed the 1 shim that was already in place and installed all 5 shims that came in the kit which sets the pressure at 700 PSI. During the test drive, didn't notice any change in the steering with the pressure reduction.

Just installed the Trans-Dapt 2025 Carburetor Adapter with the HOLLEY SNIPER EFI 2GC SMALL BORE and it worked fine when bolted to the stock manifold.
It was much simpler, but wasn't available last year when I went with the HOLLEY SNIPER EFI 2300.

The Offenhauser manifold required a lot of extra work welding and machining for the 2300 to 292 match up.

Regular gas is $1.49 and diesel is $2.37.
The difference is 88 cents per gallon.

LHD and RHD kits with or without AC are now available.

So what's a LHD, non-AC kit going to run? Assuming I have the engine, and will be running a carb for now, going to an R380.
What do I get, and what would I still need?

(Regular is still $2.95 or so here.... Diesel is the same.)
