Someone just told me that annuals for a similar Merlin powered warbird cost between $10-20K and engines last about 1000 hours between overhauls if treated gingerly (or as few as three laps if treated poorly!).
BD...Those must be Kalifornia prices on the annuals. I guess we're lucky to be up in the Frost Belt. An annual up here with extra's like prop AD and having the landing gear trunion blocks rebushed cost us $8K.
Engine TBO is a crap shoot. They can last anywhere from 30 seconds to about a 1000 hours and it doesn't much matter how nice you treat 'em (I believe Vlado can relate a story or two). Of course the harder you are on them the closer to the 30 second end of the spectrum you'll fall! Generally to get an engine to survive 1000 hours requires a top end about every 350 hours...and a close relationship with whatever god you choose to follow. Trust me the closer you get to that 1000 hours, the closer you'll get to that god! Rebuild prices are going to depend on what the heads and banks or complete engine needs and who does the work...and you get what you pay for (And the cranks can be reground but like everything else there are limits). Talent, experience and good engineering aren’t cheap. Heads/banks will be at least $20K ea. ...more if there is an issue. A complete engine will be in the $85K to $125K range, again depending on who does the job and what the core needs.
The numbers Mike G. shot out are all real close to what the operators I’ve worked with experience.
