I have to assume you have the heads off if you know what type and size of pistons you have. Do one more step and measure the stroke. If the stroke is under 4", it's a overbored 74. If it is 4 1/4" its a 80. If it's more than 4 1/4, it needs to be presicely measured to see what it really is.

Actually there is no answer until, as others have mentioned, you find out what the stroke is.

Hey i got one more ? for you shovelhead gurus. How many teeth on a "stock" rear sprocket of 1977 FXE 1200 Super Glide? Just wondering Cuz I don't have that much lo-end off the start but I have plenty of gear on the highway. Still have the stock 4 speed. Was wondering if I have a taller gear ratio. If there even is such a thing..........
