223/262 Valve size and Combustion chamber Volume

[Anonymous]

I am looking at getting a 262 and want to build it up for the HAMB drags -in a Hamb Rail I am going to build down the line. What I would like to know is what is the Combustion chamber volume of the 262 and how large an intake and exhaust valve can be fitted to the head?

the head i have a 73cc volume. i didnot check valve size. my first engin was bored .080 (3.80) with a .025 stroke. this one is bored .060 (3.78 ) stroke to 4.140. check the nunbers on block below the manafolds they should be te then date (TE62)+ some more #

Slightly off the subject, would offsetting the head toward the intake side on the block thereby getting the valves more over the cylinder and eliminating at least part of the ledge caused by the chamber overhanging the block deck help power output any? From many old articles, it seems as if the old flatlhead 6 would out power the 215/223. The flathead six was serious competition to the flathead v8 in racing, especially circle track and boat racing, the 215/223 seldom, if ever, was.

277 I6,
I have read someplace that 351w valves(1.84int. & 1.54exh) will work on the 223-262. I was looking in the the old (2005) Ford racing catalog and they had 1.84 intake and 1.54 exhaust valves( the are not listed in the 2007 For racing catalog. They were SS with under cut stems! Maybe there are some still sitting on a shelf--as they were for the new GT-40 heads. If not a set of stock 351/302w 1.84 intake and 1.54 exhaust valves whould do as there are lots of SS valves out there for the 302-351W engine.

If I remember correctly, some of the Y-block engines used the same valves as the 223. You might ask John Mummert at http://www.ford-y-block.com for his opinion. He stocks various valve sizes for the Y-block engines and sells some performance parts for the 215/223/262 engines.

The 262 also used heavy duty valves with 3/8" stems instead of the 11/32" stem that the 223 used. I suppose that you can just have different valve guides installed to remedy that situation though.

That's correct. Stock valve sizes are 1.78" intake and 1.51" exhaust. I believe most y-blocks used this size, except for the early 239 and the later truck 292, which both had 1.64" intake valve, and the ECZ-G head, which used a 1.92" intake valve.

I'm thinking a 1.92" intake may worth looking at. If it would fit in the chamber without being shrouded, then you could possibly use hi-po 292 valves and not have to make any modifications to valve guides or retainers. The overall length and stem diameter are identical.

I was doing a little searching and found that stock replacement valves-1.78" int and 1.51"exh. for the 223 are the same as the 292 Y Block. So there was a 1.92 for the 312 and perf. 292 so that will work but I'd like to get a bigger exhaust valve say a 1.55" or 1.58" . The Y-block site I found has 1.94" intake and 1.60" exhaust valves in almost stock height. Stock height is 5.090 and these performance valves are 5.060 tall. Does anyone know if the 1.94" and 1.60" valves would fit the 223 ?

I doubt .030" is enough to upset the rocker arm geometry. I would think that with a .030" shim under the valve spring to restore proper pressure you'd be good to go.

I taked to the Y-Block guy and he thinks the 1.94" and 1.60" valves will fit the 223/262. Has anyone here done bigger valves like this? :

I wish you all the best in locating an actual 262 I-6.
I've been attempting to locate one for over seven years now & all the ones that were supposed to be 262's were 223's.
