opened an engine/box up,ive had in the lock up for years, of unknown origin,to find spring clutch on a normal size taper crank and not the small tail crank as the norm...???
no engine number or id marks.. but the car was a 63 it was removed from back in 1987..again no identity marks-all i know it was grey/white but this means nothing i suppose.

its not an 850 i know for sure .bore size looks more like 1275 approx 70 mm (dished pistons) and a quick rough measurement of
the stroke- approx 68 mm which seems the same as an 850

its deffo been rebuilt at some time with a 10 thou grind on both journals.

i assume this is some kind of overbored hybrid ?

1071?

you tell me???

Bore and stroke match a 1071 , does the block have AEG 151 cast on the back ?

dunno-ill have a look tomorrow

im not getting my hopes up,its prob something sombody has cobbled together

did the 1071 have a spring clutch?????

Yes.

The Diaphragm clutch was introduced during September 1964 on the 850 models.

The 1071 had the Diaphragm clutch from April 64.

this just gets better and better

Was there a rainbow hovering above the block?

no
just a bit of good luck for a change,as normally if i didnt have bad luck,,id have none at all
