You could post the engine number and casting marks up here, including the head numbers and marks, that would give you a good start.
Didn't just buy it off ebay did you ?

There should be extra webs around the rear main seal similar to the later blocks.
The main bearings are grooved.
It should have a cast date around the time of L34 production which was July, August and September 1974.
The short motor part no was 9936518 and the block fitted with pistons was 9936519.
The head part number is 9936382.
The specs of these blocks and heads can be easily duplicated and surpassed using newer blocks and other new parts so fitting a genuine L34 engine to a non L34 just makes it harder for genuine cars to be restored.

It has the extra webbing reinforcement around the main bearing,but no "X" mark that I can see on the block. I did read however in A.M.C. magazine,that not all L34's had this mark.
When I removed it from It's dead shell and stripped it,it had inside; a crow cam,flat top ACL's,X rods and L34 diameter valves but no roller rockers or studs.
It also has grooved main bearings,but no windage tray.
The heads have a letter B cast into them aswell-what does this mean? (brock heads?)
The block number could not be found in any records, by anyone that I have talked to yet.
It is...WT352655...and as far as anyone can tell it has not been interfered with.
It checks out with the RTA and REVS as not being stolen.
I have had it for around three years,but have not yet got around to rebuilding it yet.
thankyou for your very quick reply's...hotwire1970.

The B was done the same way as the X on the side of early super duper flux capacitor titanium blocks. There are later blocks with an X stamped into the mould, but these are usually Turbo bolt pattern for commercial applications.

Sorry Byron, I must have missed this somehow. Info came from Smitty over at Aussie V8s who worked in the foundry. I have heard that the Bedford motors have them, but they would be classed as a commercial motor, the same as the engines bought new from Holden for the N.S.W. Railways scarifying machines and whoever was building cement agitators back then. I have seen a QR block with one, but the one pictured below is December 1976 308, which I would have thought would be a bit late for Bedford? (This is only people talking though. No proof.)

They were big valve heads similar to L34 but were fitted to the VB/VC HDT Brock Commodores.
They were a pollution head so my original L34 inlet manifold would not fit and required finding the correct inlet manifold, which I did by going back to the HDT.

Too early for Bedford. 4.2 and 5.0L weren’t fitted to Bedford until much later, like late 1978 into 1979 to replace Chevrolet 250 and 292 when they no longer complied with ADR’s (350 replaced 292 in C20/30 about the same time). These low comp 4.2 and 5.0L Bedford were the first XT5 V8’s, with the blue motor heads, intake, HEI dizzy etc.

I had a set of B cast cylinder heads for my L34. I bought them at a garage sale of the HDT when they were in North Melbourne.
They were big valve heads similar to L34 but were fitted to the VB/VC HDT Brock Commodores.
They were a pollution head so my original L34 inlet manifold would not fit and required finding the correct inlet manifold, which I did by going back to the HDT.
Not VB, only some VC-VK HDT engines, and also fitted to 1000’s of V5H manual Commodores for GroupA homologation. These were as you say similar to L34 engines, just had a bigger cam than L34 but lower compression.

I didn't realise just how long the TK Bedford was around for. 27 years is a long time for one model.

My RFS Brigade had a 308 powered Bedford $wd.
From memory it was a 1980 model.
Other council areas with a bit more coin swapped the 308s for Isuzu diesels,
They were a tough truck.
Cheers
