170 inline six for 3 mower blades
I traded a guy 3 mower blades for an old 170 from a 1964 Falcon. I've always liked inline sixes, especially the way they sound with a good exhaust. Anyway, I was wondering, I have a vehicle that would be pretty cool with this engine in it if I could get it to perform like I want. So what is the most torque you can squeeze out of this engine and still have a good dependability and street manners.
I was thinking
2 bbl or 2v (as they are known in inline circles) carb
split headers
1.750 intake/ 1.50 exhaust valves
hardened exhaust seats with 3 angle job
pocket port job
DUI Distributor
stock cam but maybe .450" lift, probably a kit so I get matching springs etc. etc.
Mill head to reach 9.5:1 compression
I love the way these little engine make torque, not to mention they will out torque a V engine of equal CID.
My goal 200 ft-lbs. of torque around 2400 rpm's. Should I scrap this engine or is it feasible to expect this kind of torque from this engine? I know a 200 is better because of the longer stroke, bigger bore and 7 mains but I'm not looking for high rpms, looking for torque to move an 86 ranger around. What do you folks think?

You've seen this, no doubt?
Classic Inlines - The Ford Six Dyno Room
Having had an '86 Ranger with a 2.9, I'd either reman the 2.9 or put a 4.0 in there, maybe a 5.0.
I grew to appreciate my 300 six, as well as sixes in general, but I would not invest any time in a 170. jmo....
As for an in-line out making more torque than a V, read the specs on GMC V6 truck engines and compare the 305 to the 300. It's all in the cam methinks. GMC Big Block V6, V8, & V12 Engine Data

Take the money you'll get for scrap and put it towards an engine you can work with. Not much you can economically do to increase power with that ridiculous cast-in-head intake. Not what I would consider one of Fords "better ideas" ~Bill

Compared to the 2.3L that's in it now, with a little work, should be a pretty good improvement. Wouldn't bother if it had a 2.9.

I love my little six's, but I wouldn't build a 170ci. The 170ci in stock form is 105HP, 158ft.lbs torque. The 200ci is 120hp, 190ft.lbs torque, much cheaper to obtain your 200ft.lbs.torque goal. Other concerns are matching up to your present transmission and length of engine compared to your present, with either engine. I did a V8 swap on a Ranger, but that is a well documented procedure. Good luck with whatever you do, but I would do your research. Your intended work on that little six will come close to $3000 dollars

It might be a 200, the casting number on the intake is C 8 D E, but might have just changed the head. Also heard of early 200 having 3 freeze plugs and 4 mains and then in 65 redesigned with 5 plugs and 7 mains. Don't know, the guy doesn't know about the engine, supposed to pull it this weekend. I couldn't find the block casting number C,T etc. As easy and with the interchangeability, who knows, original owner could had swapped in a 200 when the 170 blew up. How much can you save building a 2.3L vs the 170 or 200? Any time I asked about building power with a 2.3L either turbo the original engine, swap in a 2.3T or 302 or buy a new truck ha ha. What happened to the old saying, no replacement for displacement 
comparing the 4 banger to 6 shooter, not a 302!

Well, to my surprise I actually ended up with a 200, no block code, six bolt bell housing, yep it's a 200!! I have a 2.3L in a 96 Ranger, great little motor, mine probably pushing 270,000+ miles. Great for cruising or running to the store, hauling more than you can fit in a car. I just like the way a small inline 6 sounds, not the one's that are built to sound like a V8, but just the inherent grumble of a low rpm idle with the 153624 firing order, can't get that out of a V6. Especially when you lug one down with a nice exhaust pulling under 2,500 RPM's.
I just want something different than a stock truck, but don't want to go the way of V8 swap. I want something that is odd but kinda of cool ya know.

A 13B rotary from a second-generation RX7 would fit nicely and go like...well, you get the idea ~Bill
