A while ago I picked up a very derelict Triumph engine of some sort and after looking online it must be either a 7, 8, or 9, and just wondering how to tell the difference. If I can ID what it is I may find someone I can give it to who may be able to use something off it. Although its in poor order someone may be able to use some bits off it.

There's no real difference between a Super Seven and a Super Eight - both were side valve 56.5mm bore x 83mm stroke (832cc), the Eight produced an extra ½bhp!
The Super Nine was a bit larger - 1018cc (60mm x 90mm) - and also had overhead inlet valves, so easily distinguished from the Seven/Eight.

Thanks Mikes C&G !
It must definitely be either 7 or 8 then because its definitely side valve, not F head, and sounds like the mechanicals will all be the same anyway. (there is only mechanicals and a clutch on it, all the accessories are missing)

I took a couple of photos on my phone when I was up at the farm and have managed to download them onto the computer but haven't posted a photo for a couple of years now since the photobucket fiasco. I aren't registered anywhere else yet so I better get my act together and register on a different site so I can put a couple of pickys up !
I think before I contact the Triumph club people I will have a look for a serial number, that's just something I plain forgot all about while I was up at the familys farm where it is now stored (200 miles away).

Thanks blokes
Graham
