What is on the body plate and the ADR plate? As I said I have some info but would probably need to see these plates to compare to what I have.
There is a bit here, maybe look at the chassis number. https://en.wikipedia.org/wiki/Bedford_TJ#Australia
I have an order procedure for these from GMH for 1969-70 that shows GMH sold J1, J2, J3, J5, J6S and J6L. The biggest of these is 7tons (imperial) carrying capacity. In petrol engines J1-3 had a 214ci engine, and J5-J6L had 300ci. The J5 had a 330ci diesel option. As yours is kg though it must be a later example.
The 2/75 order procedure shows: CDJ1B, CDJ3B, CDL0B, CFM3B, CFN3B, CFQ1B, CFQ2B. Looking at the GVW listed for these (in lbs) i'd say yours is a 6 or 7 ton which is the CFN or CFQ which had a 292ci Chevrolet petrol 6cyl engine in them in Australia. Good news is these are gutsy engines, thirsty though. You can bolt a SBC straight in where it sits, but you don't want an engine short of a 3.75" stroke as anything less would have less torque where you want it than you have now. So this means at least a 377ci engine (4" bore with 400 crank). The 292 has a 4.125" stroke. If you do upgrade to a V8 make sure you use the flywheel off the 292, or change it to a TH400.
As for year, it has to be 1974 or later as it has kg on the plates.
