C85, C85 stroker, C90, or O200 are all options. What is your current engine?

A stroked 85 with a longer prop would be MY choice, but I'd be looking for T/O & climb performance.

I currently have a c90-8f. rebuilt in 1978 but has water damage. what would you do to the c85 to make it a stroker. would it be cheaper then a c90 overhaul. I am in canada got a quote for 32000 on complet rebuild from areo recip and 17500 from another shop

We have a C90-8F in our stock (original configuration without modifications) PA-11. We're happy with the performance. We flew the airplane for 5 decades with an A65-8 on it before going to the C90 a while back. The performance in the Northeast part of the country with 65 H.P. was adequate but our intent is to relocate to the Mountain states soon and that was the motivator for the upgrade. I like the torque of the C90 over the C85 and since that engine is on the original type certificate data sheet, no S.T.C. is required for the installation in the U.S.
