Anybody ever make a tandem seat 170? I was sitting in 1 lastnight and slid to the middle........it sure would be nice! Put a seat rail all the way back, put in some 206 seats.....like a poor mans birddog ...or a fat mans champ

Throw in some of those high compression pistons and perk up that o-300 now your talking
Are you hearing me blueldr.....

FAA aside, this wouldn't be too difficult and you'd finally be able to see all the intstruments in the pre'53 models.
Modify a seat to straddle the tunnel and use one rail per side.
Cut and weld the control column for a center yoke (although a stick would be cooler)
Move the throttle and mixture to the left side.
Re-engineer te rudder pedals too.
But, what does this get you? The 170 is already a GREAT 2 place airplane

You can always squeeze a few more horsepower out of the old O-300 by installing Continental C-85 engine pistons with chamfered tops to raise the compression slightly.

I'd paint it with some "Red" on it somewhere

On my old Harley, I had a shop shave a few millimeters or so off the deck of the heads to increase compression to 9.5:1.
That made a big difference...along with a new cam.

they already have a tandem 170....
it's called an L-19...
and if they'll quit painting it green...
( olive drab actually, to match the personality of some owners)
and put some red paint on it they'll actually go pretty fast!

Yeah, The L-19 has a stick too. Do you think it will go faster if you paint a shark on it, like a P-40?

Can I use that as approval basis to hang an O-470 on my plane?

An L-19 won't go much faster no matter how much hp you bolt on it. The SM-1019, which is an Italian military turbine L-19 clone with a 317 hp Rolls Royce turbine engine (and ugly square tail) will only go 110k at 18-20gph. But,,,,,,,,,,,,,,,,, it climbs at 2000fpm!

OK, so put the 317 hp R/R on the 170... Now that would be something

that's so the italians can catch up with the ground launched missile...
