Re: Colt engine upgrade STC
the 0320 is simply bigger.the case,crank and all the "guts" are all different. the bore on a 0-235 is 4.375 and the bore on a 0-320 is 5.125 for example
think of Ford 289 and 351 Cleveland engines..... ( I know that dates me

You forgot the Windsor, then they came out with that 302 thing.

Re: Colt engine upgrade STC
Enough of the Ford talk. Think 283 and 409 Chevy. After all they never made a song about a 351 Ford

Re: Colt engine upgrade STC
Ok I was thinking dimensions of the engines were the same when I found out you could fit the O320 without modifying the cowling. So its more like going from a 289 Cobra to a 427 Cobra

O-290 and narrow-deck O-320 are the same size case and same piston-stroke, just different cylinder bores (some experimental & airboat folks have modified 290G cases to fit 320 cyls/pistons - obviously you can't do that on a certified aircraft though)...
235 is smaller.

no that would be more like changing the o-235 to a PT6A-67F

SEAT pilot? Anyone who talks -67F has got to be either a firebomber SEAT pilot or someone who has a Hot rod AT-802.

Near the bottom of the list. I don't understand why it's not downloadable from the FAA site, have to go to Wag
