[ridgerider]

i have a 1968 shovel and the rear cylinder has cracked at the base...i found a set of 1978 cylinders on fleabay...will this bolt up and fit?  forsee any problems doing this

Thanks

it seems to me that thoes cylinders are the same if they are 74 inch, but the base was made thicker for the 80 inch because of the cracking issue.  vern

Just check the base flange thickness ,the late 74" motors had 80" type barrels, your studs may not be long enough,
you can tell them apart by the number of fins , but I can't remember which has what.
I'm sure some one on here can tell you, or maybe an 80" owner can count them for you.

   You'll have to either replace the studs with longer units (approx.3/8"), or pull & remount yours with loctite, replacement is best. Also you should use late style 9/16" head nuts with the stock "wedge" washers.
   As for bore, if your lucky, you've got 74" barrels they stat at 3.438", but if you have 80" barrels, they start out life at 3.498", and are .060 over 74" size, not a whole lot of life left in them for overbores. ...Jeff
