What engine have I got.

[Min]

Hello all, I am new to Triumphs having had a Morris Minor Traveller as an every day drive for nine years. Have purchased a bag of bits resembling a Triumph Herald convertible. Having great fun looking at bits which had apparently been "done" The engine number is GD26ESS which I believe is a factory replacement, but what capacity. the log book says 1147 and the car is supposed to be a 1200, but I thought the GD engines were 12/50? also discovered there seems to be no fuses...think I may have blown something up trying to get her to run, changing coils etc. carb seems to be dripping when ignition not on. Oh the joys of getting a car to the yipee lets have a drive Any help would be wonderful, and encourage me to ask many more questions which are cuing up in my head. Thanks

Thanks for that, how much difference is there for spec or carbs etc is there if any? Am looking at taking off carb and boiling it in water to clean it and see if it works. also dont seem to have a drain in the manifold, seems to have been blanked off, not sure if that is good.

Quite possibly no difference at all, especially given that it's a "factory" replacement. Typically, as I recall, the GD engines used a different camshaft (as per early Spitfire). That's the most significant change, although there might also have been slight differences in compression ratio and such, but then heads are easily changed, so.... ???

GD and the Hot cam GA (GA178101E on) have the same specs.  

GD engines were fitted to GA cars from Comm. No. GA235,000 (late 196.
