Replacing REM40E with REM37BY?

[Michael Horowitz]

I'm told the 37BY is shorter and runs cooler then the 40E. The 40E's
are installed in a certified a/c.
Would an IA object to me changing to the 37BYs (I need the shorter
length), and what effect will I see on performance? - Mike

you would probably see some plug fouling if using leaded fuels.
my O-200 was swapped to REM40E's from the standard REM38E's for
100/130 Avgas use and has no real problems with plug fouling.

I think what you need to do to get useful answers from the group is
indicate what fuel you will be using.

OK, this is an A-65, with the STC for autogas, so I can run either or
both Avgas or Autogas - Mike

I know that the 37BY is FAA approved for your small Continental engine.
