Stroking the Continental.

[Capt.Crash'n'Burn]

No, I'm not making a euphamism here, get your mind out of the gutter!!!

There's 4.5" stoke cranks avaliable for the Lycomings, is there someone who makes long stroke cranks for the Continental??

What is the maximum stroke that will fit in the 550 crankcase??

Well, 5 days and 120 views later and still no reply.

I take that as meaning that stroker cranks aren't available for Continentals.

the 470/520/550 all share a common case. In our recent 520->550 conversion, we had to change the connecting rods out for some which had a machined-out area for the crank counterweight throw to have clearance. (this is one of several differences between the 520 and 550 -- we did it piecemeal as a learning exercise)

My terminology may be off on the above. The difference between the connecting rods, IIRC, was something like 1/4".

It's damn tight in there already. I think the case is containing as many cubes as it can with the 550, which is a stroked and bored 470.
