Hello folks!
I'm considering purchasing a finished RV-7 fuselage, that has been painted, but is still sans engine and panel.
On the panel side, I'm tending towards the G3X, since I have a few hundred hours under the G1000 on Cirrus and Cessna airplanes...
On the engine side, I'm following the advice of some around the forum and looking for a nice rebuilt engine, from a certified airplane.
So, today I found this IO-360-C1C6 that was taken from an Arrow III or Arrow IV. I looked at the TCDS and found this description list:
So, if I follow the description:
- it's a standard injected engine, 200HP, 8.7:1 (low compression! Good!)
- rear mounted injector with a 14-degree inlet adapter (horizontal? Vertical?)![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
- Bendix S4LN-1227 magneto (huh?)![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
- Counterweights (low vibrations ! good!)
In plain english: Does it fit the RV-7 cowl for horizontal induction? (no scoop?)
Will it fit the standard dynafocal mount?
Can I upgrade the magnetos to electronic ignition?
Should I use the Arrow III's original propeller (keep vibrations in check)?
Thanks a lot for any light you may shed on this. I'm an electronics engineer, more comfortable with the electrons and silicon than with treated metal and engines![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

In Brazil. Maybe purchasing an RV-7 fuselage...

IO-360-C1C6
200 hp (149 kW) at 2700 rpm, Minimum fuel grade 100 or 100LL avgas, compression ratio 8.70:1. Same as the C1C but with a crankshaft with one 6.3 order and one 8th order counterweights.[4]
IO-360-C1C
200 hp (149 kW) at 2700 rpm, Minimum fuel grade 100 or 100LL avgas, compression ratio 8.70:1. Same as the C1B but with a 14-degree fuel injector inlet adapter and an impulse coupling Bendix S4LN-1227 magneto.[4]
IO-360-C1B
200 hp (149 kW) at 2700 rpm, Minimum fuel grade 100 or 100LL avgas, compression ratio 8.70:1. Same as the C1A but with Bendix 1200 series magnetos.[4]
IO-360-C1A
200 hp (149 kW) at 2700 rpm, Minimum fuel grade 100 or 100LL avgas, compression ratio 8.70:1. Same as the A1A but with a rear-mounted injector.[4]
IO-360-A1A
200 hp (149 kW) at 2700 rpm, Minimum fuel grade 100 or 100LL avgas, compression ratio 8.70:1. The base fuel-injected model, a four-cylinder air-cooled, horizontally opposed, direct drive, fuel-injected, tuned induction engine with oil jet internal piston cooling. It includes provision for single action controllable pitch propeller.[4]
So, if I follow the description:
- it's a standard injected engine, 200HP, 8.7:1 (low compression! Good!)
- rear mounted injector with a 14-degree inlet adapter (horizontal? Vertical?)
