does anyone know if there is an STC to upgrade engines on a straight 170?

possibly an 0-360?

thanks

Here are two listed on the FAA's website:

Del-Air's Lycoming O-360 STC is only listed for the C-170A and B, but I'll bet Harry would install an O-360 for you under a field approval.
His number is (559) 784-9440.

That one STC is interesting. A Lycoming 320 with a four bladed prop. Any one ever see one? Bill K

Ooops guess I'll take off my Hartzell and look for a four paddle prop.
