DavB Posted November 24, 2013 Share Posted November 24, 2013 hi allJust bought a 1963 herald and thought it had a 1200 engine but think its a 1300 engine number GE 78962HE is this the high compression onw?and what is the horsepower, and is there a way i can improve the performance i.e. better cam or twin su`s etc.sorry for being such a noob its my first time on this forum and my first herald many thanks in advanceDav Quote Link to comment Share on other sites More sharing options...
Mark Hammond Posted November 24, 2013 Share Posted November 24, 2013 It is a small crank 1300, the one everyone wants. Cam change with a pair of SUs could get it to 75bhp as per MKlll Spitfire and beyond, careful, bottom end can get fragile. Stock bhp was 61 when new in the 13/60.Mark Quote Link to comment Share on other sites More sharing options...

Sheepy Posted November 24, 2013 Share Posted November 24, 2013 Hi mark, How can you tell if a 1300 engine is small crank or not from the engine number?For example, engine number FD****HE Thanks, just curious if the engine I have is small crank or not.CheersShaun Quote Link to comment Share on other sites More sharing options...

HMaze Posted November 25, 2013 Share Posted November 25, 2013 FE Spitfire Mk3 (US) small crankFK Spitfire Mk 4 (US) large crankboth low compressionthere is also FL, 1500 for swedenand FP, 1500 in the midget.And there is the odd GK(!), a 1200 from the german amphicar.So Triumph did use the same prefix for two different engines!Cheers,Harry Quote Link to comment Share on other sites More sharing options...
DavB Posted November 25, 2013 Author Share Posted November 25, 2013 Thanks for the info guys its much appreciatedIm sure in the coming months I`ll have lots more questions to ask :) :) Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted November 25, 2013 Share Posted November 25, 2013 GE is 13/60 Herald. Small-crank 1300 and about the the most tunable of the 4 pots if you want a screamer.Nick Quote Link to comment Share on other sites More sharing options...
Scimher Posted November 26, 2013 Share Posted November 26, 2013 ..I didn't know anything about the differences in crank in engines of the same cc.........What would my 1300 Dolomite engine, no. DH87728HE be..??...(It resides in my mid-sixties 1200 convertible....) Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted November 26, 2013 Share Posted November 26, 2013 That will be a large crank 1300 similar to the GK series used in the later 13/60. Not so able to survive high rpm.Nick Quote Link to comment Share on other sites More sharing options...
