Overhaul Question - 1972 Arrow II

[ready1998]

Hi Everyone - first post here!

I have a 1972 Piper Arrow II that was overhauled in 1982 (yup - I know. Been a while) by Mattituck. She currently has 850 hours SMOH, runs with compressions in the mid 70's, and oil analysis have come back clean so far. We're currently tracking the Oil Changes (only have done one so far since my Annual in April) and keeping our fingers crossed that the engine remains healthy. We're hoping to get another 2 or 3 years out of her before making the investment for an overhaul.

Now this engine was the IO-360-C1C varient - the one that had the poor TBO 1400 hour until later modifications (a redesigned cam shaft I believe) were done in 1973 and beyond to increase the TBO to 1600.

My question is, would Mattituck have been able to further increase the TBO during that first overhaul?

I ask because I'm curious to know if I were to get another Overhaul done, will I always be limited to the -C1C's 1400 hour TBO? OR should I just pony up the extra 10-15k and get a new engine??? I mean, Turbo'd be nice

Any and all help, suggestions, flames, and rants are appreciated!

Thanks,
Bill
