I have a friend that owns a 1958 J35 with an IO 470 C that wishes to do a engine STC but I am not that certain what other horse power increasing STCs are our there for the J model. Does someone else?

Oh yeah, depends on the amount you want to spend. The IO-470-C is a good engine, but is getting a little old. For instance, these may have had the Beech 278 prop, ( a good prop) but support on these is getting less all the time for overhaul etc.

Option 1.) Get the IO-470-C and prop overhauled.

Option 2.) Get STC upgrade to IO 520 or IO-550 and new prop.

The J35 is structurally strong enough for the larger engines, the airframe has higher speeds than previous models. But add tip tanks for the longer trips.

I'll through some numbers out here, but call around and see what the current pricing is. You''ll spend $25K to $35K to get your current IO-470-C and prop overhauled. And to upgrade to a IO-550 and prop with STC will be around $45K to $55K
