Re: 272 cylinder on a 254?

IIRC, the 254 has a shorter stroke that the rest of the members of that family. (I remember SawTroll reminding me of that a short while back) So that lets the rest of the family out. The 272 cylinder also has a spigot or flanged base that fits down into the crankcase, the 254 and the rest of the family use flat based cylinders.

So, unfortunately I think you re out of luck. If and only if you could put the 272 top end on a 254 the cost to doso would be more than just buying a 272 and rebuilding that.

Actually the stroke is the same, but the con rod is shorter than on the 262 and 257.  ;)


if the con rod is shorter,maybe the piston pin to crown height is taller?

Or the cylinder is sitting lower relative to the crank?

I don't know the details.
