O320 upgrade conversion on COLT

[gliderman]

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.

Enough of the Ford talk. Think 283 and 409 Chevy. After all they never made a song about a 351 Ford

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
