I read somewhere one time that HD made a 1300 cc pan head.
Where all pan heads 1300 cc ?
Did they make the first pan head in the early 80s ?

 

Panheads came in 61 cu in (1000cc) and 74 cu in (1200cc). The last Panhead Harley made was the 1965 model.

 

Alas you are correct as a friend of mine had told earlier before I posted this. I also checked on Wiki and it said the prior FL models had the KnuckleHead also in 61 and 74 (1200), but the old UH models had a FlatHead 1300cc, and then the FL Panhead came along with 1200, and then after it the FL Shovelhead came originally with 1200 (with a 1300 option) but in 1981 the 1300 became standard. (of course now it's 96 or 110 CVOs)
So 1300 started the Flathead but 1200 kept coming back for awhile. The Panhead was the Harley that was out when I was in High School and was a favorite chopper engine in the late 60's. If I remember correctly it was the first to have the electric start and they called it the Electra-Glide.
Thanks for the correction.

 

UH/ULH were 80 cu inch side valve motors with a piston displacement of 78.75 cu inches, compression ratio 5.2/5.7 to 1 and horsepower rating of 9.44.

Not exactly high performance by todays standards and gives a glimpse of why MoCo went to overhead valve system.
