Which IO-540's

[Greenley]

Exploring engine options, but still have a lot to learn. I know vans sells the IO-540-D4A5 for the RV10, are there other variations of the IO-540 that are reasonable to use (do not require cowl or other FF forward mods)? Planning a variable pitch prop. Yes I searched the forums, but could not find this.

A search on vafarchive.com yields this: http://www.vafarchive.com/msg/rv10/t2003283003#1255

Incidentally, someone posted an ad in today's VAF classifieds parting out an Aztec and has two IO-540-C4B5 engines for sale.

I have an IO-540-N1A5. A little heavier crank and 5th and 6th dampers, everything else the same.
