Hi all,

I'll start off with honesty :)
I have a series 3 Hillman Minx and i bought a 1725 Commer van engine for it. I was wondering if anyone had info on Commer engine numbers and what they mean?

I have attached pictures of the numbers i can see.

TIA, Justin

Hi and welcome. Doesn’t mention engine numbers in the workshop manual unfortunately sorry so I can’t help. I’m sure someone will be along soon with the answer.
 
Hi and welcome :)
Sorry I can't decipher the numbers on your engine but here's a link to our homepage that explains the difference between the Rootes engines

Depending on the age of the engine it could be anything between a 1500cc and a 1725cc, a picture of the side of the engine with the oil gallery plugs showing would tell us if it's a three or five bearing crank.
 
The long number cast into the block beginning with a 7 looks to be a Chrysler part number, so a late 60s/70s block. The important one is the stamped engine number on the faced section above the fuel pump. I am not so familiar with earlier engines, but on the Hunter range from 1966 the engine number was the same as the chassis number. Ryton-built cars began with a B, Linwood with an L. For example, my Rapier begins LG342, (LG342 is for 1971m.y. Linwood-built Rapiers with 1725cc high compression pistons and twin carbs). As yours doesn't begin with a letter, it suggests it wasn't built at either Ryton or Linwood but at one of the smaller plants, supporting the idea it came from a Commer van. I probably have the prefixes for all of the arrow range cars and engines somewhere, but not any other models. You could try the Rootes archive centre! https://www.rootesarchive.org/

Brilliant information. If you could publish the list of engine that would be great as there are a few of us non-Commer Rootes engines installed. Maybe John could add a link to it on the home page
