I am looking at what is claimed to be a 262 six. I have a decent 223 six already for my 59, but wonder if the bigger engine would serve me better. I will be doing some towing, but mostly am looking for a better mileage driver.

Does anybody have any experience with the 262? Is it noticeably better than the 223 powerwise? Is there a big mileage cost to the bigger engine?

The casting number is C4TE-6015-CD, is this really a 262? How do you tell the two engines apart?

I want to avoid the power trap - you know, once you start looking for more power you wind up with a 8 MPG 460V8. But on the other hand, if this engine looks like a 223, performs like a V8 with the economy of a V6 - but dream on.

 

I thought I had read somewhere on the board that the 262 has the distributor on the opposite side of the block ... but I may be wrong.

 

No, I looked it up - it is a stroked 223, but the same block

 

Ya.. a 262 and 223 are interchangable in just about all parts.. Heck, If I could find a 262 Id put that right on in and just bolt all my ad-ons on

 

I'm pretty sure the blocks are slightly different ... maybe I was wrong about the distributor, but I think there are internal differences, like more reinforcing ribs in the casting.

 

The 262 block is thicker and has casting ribs on the outside.. but al the parts are interchangable.. Even the head will bolt on..

 

Yes, it is a truck engine, according to the website I was on. That is one reason I worry - HD industrial engines are not known for their mileage or performance.

I can get a 300 six for less money, and that has the potential of adding efi should I ever wish, and has hydraulic lifters. Does the 262 have solids?

Also I already have a 223 that I have never started.

 

WillyB.. What site U getting the info on? Id like to take a peek also

 

For the most part they are, but they are not completely interchangable parts wise as some parts are 262 I-6 specific.
Here's some Intel I borrowed from 'Bubba" because I could find my post that had the Intel I researched.
They were made from 1961 to 1964 - (to 1965 for industrial and stationary equipment use).
They have a larger Bore of 3.718 x Stroke of 4.03 than the 215 & 223 engines.
The 1961 to 1963 were rated at 132 H.P. & 224 Torque the 1964 & 65 is rated at 152 H.P. & 238 Torque.
It is a Truck only motor that was optional for the 1961 to 64 F-600, C-550, C-600 (the tilt cab trucks) and B-600 trucks Door ID tag code B.
In 1964 was offered in the F-100, F-250, and F-350) light trucks Door ID tag code B: Used in1964 & 1965 DIVCO trucks as the "G" series motor.
Externally the 262 will have Dual Primary Belts from the Crankshaft to the Water pump & Generator, has a gear driven cam instead of the chain cam drive of the 215 or 223 light truck engines.
The crankshaft gear is lubricated through a flat on the No. 1 camshaft bearing.
The use of a Carter Fuel Pump that is mounted on the timing cover and driven by an eccentric on the timing gear (the blocks have a cast side fuel pump mounting boss, but it was blocked off).
In 1964 the fuel pump location moved to the side of block, like a 223 and was driven by an eccentric off the cam.
A water heated Spacer at the Base of the Carburetor was used to Prevent Icing.
It Had a Forged, rather than a Cast, Crankshaft.
Equipped with a Positive Crankcase Ventilation system.
The distributor is mounted on the right side of the block towards the front. There are 8 bolts holding down the valve cover, and came standard with a full flow oil filtration system.
Probably the best external identification on a 262 block are the added ribs on the inside of the block and there are extra reinforcing ribs that run for and aft almost the entire length of the block to give added strength to the upper Crankcase area there are some massive ribs above pan rail too.
The 223 blocks don’t have these added ribs so this makes a 262 block 20 pounds heavier than a 223.
They will replace or swap in place of a 215 or 223 by switching some parts depending what the motor is going into.
223 heads can be used on the 262, but different years use different temperature sending units.
Also the early 223 heads will have to have the head bolt holes in the head drilled out so the 1/2 inch head bolts can be used I would think a 215 head will also fit since the 215 & 223 are very close.
Intakes interchange, as will exhaust manifolds, but check the header pipe size and location where it fits on the manifold.
Rocker arms of all types interchange.
Three types of connecting rods were used.
Oil pans should interchange, but may have a larger capacity or a different sump location.
There are several parts that will also interchange with the Y-block V8’s, I have a quite a bit of other info for them if you need it.

 

Thanks, Colonel - I was hoping you would chime in. The details are interesting, but the real question is which engine would serve me best, the stock 223, the 262, or the 300.

I am not interested in speed - 70/75 is as fast as I go empty and 55/60 when towing. I am downsizing my rigs, have a small boat and trailer now, and a 12 foot Scamp type camper trailer. (will pull only one at a time!).

I will be using it as a daily driver so I also want to keep up with city traffic - but have no urge to beat someone away from a light. (or not much of one!) Also, when traveling, pulling the camp trailer, I don't mind dropping a gear over a pass, but do not want to become a hazzard to navigation. I would like to keep up with the big trucks over the Grapevine.

One thing I do notice is that the 223 is a square engine (bore and stroke about the same), as is the 300. The 262 is over square, that is the stroke is longer than the bore. I have always thought the longer stroke is better for low end torque - and remember we used to want square engines, but not why that would be better. Any thoughts on that?

Mainly I am looking for the best compromise between towing ability and economy. I went 6000 miles over two months last summer, and had hoped to do the same this winter.

Anybody have a suggestion or comment?

btw, I am running a 4 speed stick into a 310 ratio 9" rear with a locker.
