Bore & Stroke a 223

Anyone ever contimplate the above?
It looks as if I might have a 262 I-6 Crank & Cam shafts, Timing Gears, etc. to do this w/.
Wont know untill the engines apart, it looks real trashed & overbored several times already, so these are a few of the parts I'm hoping to salvage from it if it's to far gone.
Any input would be real helpfull.
 
The 223 has a 3.62" bore, not sure what the 262 is. I doubt a 223 could be bored any where near the 262.

There used to be a spec sheet on the Clifford Performance site that stated a 262 crank could be used to stroke the 223.

I'm sure it's still linked on the site. You just may have to dig a little.

My book states that the 262 is;
B&S 3.718x4.03
The 223 is;
3.625x3.60

What other specs would you require to figure out what's possible?

According to the 262 manual the only real difference between the 223 block & 262 block is 20lbs extra re-enforcement ribbing in high stress areas.
But I'm open to any & all information regarding others experiences in building performance I-6's.
I've only had experience in re-building engines to factory specs & some head swapping in the past.

We will help you dig deeper!

The blocks on early Fords were well documented in an early book I found on US cars. I saved the details some where, but can't find it here. I remeber that up untill the late 1960's, all six cylinder engines had very long rods, about 1.75-1.85 times the stroke.

The key to unlocking this is the deck height of the block.

CAN YOU GO MEASURE THE DISTANCE FROM THE CRANK BOLT TO THE CENTRE OF THE HEAD GASKET?

To the nearest 1/16 th with a steel rule or piece of wire.

From there, I can work out what you need to do.

Your 223 has a piston about 1.86" deap. I don't know what size the rods are, but the I-block is just a Y-block derivative, and its likely it has Y-block rods which are about 6.24" long. The pistons, plus half the stroke, plus the Y-block rod would indicate a 10" deck height.

Info from http://www.beckracing.com/slvpg44.htm says:-

Stock size 3.625" diam

1954-64, 8.3:1 comp;

Flat head piston;Comp. Ht. 1.858"; Pin Dia..9122 Offset;

Part No 1079 in Std.;.020;.030;.040;.060

So the sizes are right up to 3.685", and the 262 can be 3.718".

My bet is the 262 was a shallow piston engine with the same rods and a beefed up block which does not have a longer deck from crank centreline to gasket. 20 pounds isn't much extra weight.
