I have a complete 1970 Norton 750 engine and gearbox ,primary and swing arm in one piece in the cradle. Engine turns over and gearbox is free. Engine Number is 138458 (stamped on the gearbox only) making it I believe one of the last “S” models. No broken fins on head or barrel. My question is what's it worth in USD. I do not have a frame or title for the engine. I am in Houston Texas. Please e-mail for pictures at oscar.thackery@rhi-ag.com
My thoughts had been to keep it and find a frame however the cash will help me fund my 850 mk 3 restoration. Thanks

Not that it matters in regard to its value but the last 750 'S' model is supposed to have been 135088.
 
Maybe it is from a Fastback Mark II. When i checked the various sites with information on engine numbers I may have misinterpreted the data. What do you believe I may have ? was this engine number the S specification ?
 
It makes a huge difference whether it's running or not, and if running, whether it's in good shape or smoking & rattling.

One of those sites wouldn't happen to be Norvil Motorcycles by any chance, as the some of the model identification information there is misleading simply because they've left so much out. :cry:

'138458' was likely to have been a Roadster, although there is a reasonable chance that it could have been a Fastback, but more chance it was a Fastback MkI rather than MkII.

The engine number stamp would probably have had the 20M3S prefix (thus: 20M3S/138458) however that prefix is normally found on all camshaft driven points engines right up to the end of 1971 production, so the 20M3S prefix doesn't automatically identify an engine as being an 'S' Type.
 
If the engine complete with gearbox ,Primary and cradle is only worth maximum $700 i will keep it and look out for a frame or split it to sell the parts. Many thanks for your interest.
 
JUst my 2 cents, what I've seen items sold for. Engine, $1000, gearbox $300, cradle and swingarm $100. Primary assembly $250.
 
Here in Australia that engine, primary and gearbox would be worth $3,000 wheather going or not, I have seen 2 complete Atlas motors in my loycal British shop and they were asking $2700 for each one, mine you they are still on the self after about 3 years now and thats not knowing what they are like inside.

I've sold three complete engines (with tranny & primary) for $1,000 each.

All three needed total overhaul.

I've also bought two complete engines for $1,000 each.

Turned out one of those two is still just fine, with e-start; it's in this bike till I build the VR880 engine...

I do not believe that the engine i have would need a full overhaul however it would be buyer beware and I would imagine that as a precaution you should always pull the head and primary chaincase cover to inspect what you have. I am going to list it at $1500 . Thanks for all your advise
 
Going by the mind set of Norton'rs stuck in '70's price memories - As a complete ready to go cradle tranny and engine it would be tempting to bargain for it at $3000, parted out about 3x's that but just unknown parts condition with everything there, $1500 sounds like it'd sell at your loss of inflation of money unit value. Call a few big vendors Baxter's Norvil, Old Brit's, British Spare's etc and ask about just AMC shell or engine cases, or crank or cam drive kit or head to see what the scope is for real.
 
I did make a few further enquiries and it does seem like I would probaly make more $ if I sold the engine gearbox primary and cradle with swing arm seperately. The thing is it would be a shame to seperate all especially if someone out there has a rolling norton or similar and wants to complete their special.
 
Yep part of the life and times of rationalization insanity on the worth of our hobby craft left overs. The more ya make what ya got worth while the less its worth to anyone to pay for it all. So be$t path is take it all apart and list each item separately but mention on each sales ad that you have all the rest of the parts from same assembly in other ads and will do a deal on shipping if orders combined.

YAHTZEE!
 
I'm just a silly old fart who haunts this forum, however I'd say one thing - avoid selling any thing BEARs. If you have to fund a project , work harder and pay for it. I have severe regrets about some things I have sold.

First licenze new in Italy on 9 august 1969: now she is mine, but i remember at those time.
Norton serial numbers say the bike is a S type!.
Wrong, she was at first and still is a ... Fastback!
Ciao.
