View Full Version : 59 Lark

11-22-2009, 07:11 PM
Just bought a 59 Lark 6 4dr and its got an ohv 170 in it and I was just wondering if anybody could tell me if this is the original motor or not.I've got a shop manual and it say that all 59's and 60's had flatheads in them.

The number stamped in the upper left hand front corner (on the side) of the block will tell if it is the original engine. Post it here and someone can look it up.

[Edit] No, I didn't notice the ohv mention above.

Welcome! Post your engine number and we'll tell you if it was built the same year as your car, at the very least. If you buy your original production order from the Studebaker National Museum in South Bend, that will tell you what the original numbers were. Your body style could come as either a 259 V/8, or your 6 cylinder version. Different size brakes, & a thinner gauge frame for the 6 cylinder cars will be some of the unique signs of a Lark VI. Good luck.

He says it's an ohv engine. Wouldn't be correct no matter what it's number is! The Stude OHV 6 didn't debut until 1961.;)

1963 Cruiser
1960 Larkvertible V8
1958 Provincial wagon
1953 Commander coupe

/Cut/The engine number and/or the head casting and date code should help figure out what he has for sure, eh?

Yes the Engine serial Number (STAMPED INTO BLOCK) will tell us what year the OHV 6 is, but I'll credit hops with knowing an OHV Engine when he sees one though. [^]

Be advised that if it turns out to be a Studebaker engine, it could be either a: '61, '62, '63 or '64. :)

I'm pretty sure it's a tranplant cause like I said my shop manual says 59's and 60's have flathead 6's.I'll check the # on the block in the mourning it's raining like crazy right now.Isn't the ohv 6 a better motor anyhow,any idea about the hp on this thing anybody?Guy I bought it from had no idea about the car being original or not.Honestly me neither,I'm just now starting to look things up just got shop manual yesterday.

Ya but flatheads are cooler lookin.

11-22-2009, 08:54 PM
So the Engine resembles the PICS in your '59-'64 Studebaker Chassis Parts Catalog or Shop manual of the '61-'64 170 OHV 6 then? [^]

GOOD, at least it is a Stude. Engine then! [^]

The HP is 112 at 4500 RPM, it has considerably more acceleration in the mid RPM range than it's "L" head brother! The long ram Intake Manifold, simi-hemi combustion chamber and large canted Valves contribute a lot to that.

With the stock gearing it is quite peppy, but most 6's are a bit too low geared for the Interstate without Overdrive to prevent overheating and engine damage.

The Dana/Spicer model 23 (or 27) axle can receive other ring & pinion ratios, or you can replace it with another complete unit or a heavier model 44.

You can clean & read the tag that is usually on the rear Axle cover under a bolt at about 8:00 for the RATIO. :)

Checked the # on the block this mourning its S174108, so what year would that make the motor?Also did the bumpers have bumper gaurds on them for the 59 or not? I'm just trying to find out what's orginal and what's not.

11-23-2009, 01:55 PM
Bumper guards are like side view mirrors, wheel covers, radios, heaters, tinted glass, cigar lighters, clocks, back-up lights and all other accessories, they are options. You have to order the car with them or add them at the dealer at extra cost.

It DID come with 5 real blackwall tires, 5 wheels and a jack though! :D

My first car was a 59 Lark 4 door 6 cylinder auto, Seamist green. When the original engine cracked the valve seats, I installed a 61 OHV engine I bought from a local junk yard in South Amboy, N.J. (Cutler & Hammerling if memory is correct). It sure would be a hoot if that was originally my car!! What size are the brake drums? If its got the 11" front & 10" rears, then it has to be the car I had!!

60 Lark convertible
61 Champ
62 Daytona convertible
63 G.T. R-2,4 speed
63 Avanti (2)
66 Daytona Sport Sedan

Don't know about the brakes yet,but the car is blue.Well most of the car anyway.The front clip has been primed black.I bought the car from a guy in Lexington NC,who bought it from another guy that lived up closer to Virginia.So could be,you never know:D

S174108? That's odd, the only S 6 Cyl. Engine number that has 6 digits is the S-106,101 which would make it a 1960 170 FLATHEAD!

For Engine I.D. it's on our mainpage, you go to "Technical Tips, Specs and Data", and choose
"Studebaker 6 Cylinder Engine Identification"


Has to be a bad number, renumbered OHV or a Flathead! [:0]


11-23-2009, 08:31 PM
It must be renumbered then cause it its not a flathead.My only question now is are all the ohv 170 the same for 61-64 or are there any differences between them?

11-23-2009, 08:45 PM
There were Chevy 6 cylinder engines offered in 1965-1966.

Remember I told you in one of the above posts that your Shop manual would show the unique shape of the engine i.e. valve cover etc. so you can see what a Stude. OHV 6 looks like.

The most noticeable difference in Stude. OHV 6's is the late '62, 63 & '64's have a full flow spin-on oil filter mounted at the right rear lower area.

The '61-early '62's if equipped, would be on top.


11-23-2009, 09:20 PM
Mine would would have to be a 61 then cause the filter is on the top

Do you have a picture, or can you email one of us one?

11-24-2009, 11:43 AM
Here is a pic of the motor
And here is the block #

Hops, being that you've posted pics, would you mind posting pics of the entire car? We here on the forum like to see Studebakers, in any condition. :)

Just wanting opinions on which direction I should go with my Lark since the motor isn't orginal to the car?

11-26-2009, 12:05 AM
The newer engine is an improvement, and thats a good thing! It depends on how much money you want to put into it, but I would give it a coat of paint, inspect the brakes to make sure they are safe, put some new steel belted radial tires on it, and drive it! Have fun with it, thats the most important thing.
