223 performance build horsepower estimate?

[Anonymous]

Ok, my '64 Ford Custom has a great running 223 with no blowby, clean of sludge inside and consistent compression figures. I believe it likely was rebuilt within the past few years.. I'm considering a mild buildup just to see how this little mill will do. I'm not expecting a real tire scorcher. My plans include a 2100 1.12 Autolite 2bbl. atop a Stovebolt Engine Co. Adaptor (or a homebuilt intake), a performance reground cam cam by either John Mummert or Daytona Cams, Barker high lift rockers, a homebrewed header and the 300 Duraspark dizzy conversion.. I'd like to get about 175 hp at 4500 RPMs., about the same figure as a moderately built Flathead V8. Would this combo do it? Does anybody have suggestions for anything I might not be thinking of? Also, what would be good net lift and duration figures for the cam? I want to keep this a budget build without machine work as a 300 will likely be swapped in eventually.

Or am I totally out to lunch, insane, and should just blow this idea off for the 300 now?

Iknow that I'm asking a lot, but you guys really know Ford sixes.

Thanks for your help..

I'd look at murdering a pair of stock intakes to direct mount two small Autolites, and would put each on a water-heated plate. The water will give you a nicely regulated carb temperature.

You said no machine work; I took this to mean no block decking, valve resizing etc. For cam grinds - if you could see how the ports are (got a spare head?) then intuitive decisions could be made about the flow. Personally, I'd favour longer duration with gentler ramps over a really snappy grind. You'd need to balance that against static compression to see where the efficiency was lost.

Offenhauser, Fenton, Edelbrock, etc. make 4v, 2v, Duce-Paks & Tri-Paks for the 223 I-6 & can be found on e-Bay, Hedman, the last time I looked, still had a Header listed for the 223 I-6.
Go for a B&B, Minimal P&P, w/ Oversize Valves & Stiffer Springs.

That would look the cleanest, I must admit.

And keep in mind that this engine has 4 mains, thusly do not hammer too hard.

dont forget about clifford.they got a 4bbl intkae for the 223.

I'd go with a 264 duration .450" lift 110 lobe center 220 @ .050" & maybe should go with larger valves so it can breath, deck the block .030 & head .010- this way you won't need high ratio rockers.

Will the 223 and 262 take a .030 deck and still have enough deck materal? Will they take a .040 deck and still have enough deck strength? Also why only .010 for the head?

 

[texas_rat_trap]

There is plenty of material on block to deck .030, but not enough for .040, so you go .010 on head to reach a combined total of .040 to raise compression ratio to close to 10 to 1 . From what I remember. I am currently building this 223ci combination

Called Hedman and they do not carry Header anymore, but boy do I wish they still did
