For sale a set of cylinders with heads from unknown sled. This is what I came up with from the P/N on the cylinders. 70-79 Ski-doo 368 F/C type 371. P/N's 913980 and 913970. The sleves have surface rust on them and a honing will need to be done. Heads are in superb condition with no damage to spark plug treads

. Not shure what to be asking for them so you make a reasonable offer. I dont want to split up the set but if a good offer comes along maybe. If you have questions or need more detailed pictures feel free to ask. Thanks for looking!
