Finned and Edmunds style H/C Heads

I found out that Empire Motors Inc in Texas is casting reproduction Normal, Finned and Edmunds style H/C Aluminum Heads. I have an email into them for pricing.

The also have Edmunds production intakes and exhaust for the Straight Eight motors. An Ad I saw for them is claiming 212hp from a 327 with this setup (manifolds and head) using the stock Carb.

I am going to try to get their price list and specs to post here for those that are looking for a little extra 'pep' out of your Straight 8.

BTW they also make reproduction A/C mounting brackets and pulley setups for 54 and prior years.

And of course they have always made reproduction and H/C heads for pre-war Packards.

Just thought I would pass along the information.

There was a thread at the AACA Forum, earlier this year, where someone was asking about Empire Motors Inc, of ElPaso, TX. The responses weren't rosy, but due to that club/site's position with regard to publicly commenting on vendors, the participants typically directed the poster to PMs for more info.

With no salient details, most of the thread isn't much of a read, but the AACA Forum site appears to be down for yet another round of maintenance (hoo-boy, here they go again).

I suggest you ask around about this vendor at the PI meet next year, and post back with any "qualified opinions" you find.

Sraight 8 with high compression heads and pistons, 4 1bbl downdrafts, and a hot cam, as on the 1953 Motto bodied Trevoux Carrera Panamerican Packard, and you would probably have close to 300 hp...

They also informed me that the website is about 2 years out of date, but they recently spent about $400,000 on casting tooling and plant improvments.

Pricing is based upon finish, and also desired compression ratios so anyone interested would need to call them for more information.

I just thought I would pass this all along for the folks that are interested.

I really do like how those aluminum finned heads look on the Straight Eights.

I guess I need to figure out what compression ratio I want before I ask for pricing. I wonder what a good compression ratio would be for a bump in performance, but still keep it 87 octane friendly. Any suggestions?

C/R Vs. Octane: Easy rule of thumb to remember, take your compression ratio, multiply it by 10, and there's the minimum octane you'll need. Not very scientific, but it's accurate enough for 99% of the people here (including me) to go by.

So 8.7:1 would be what I am looking for then.

You could go 9:1 if you make sure the timing's absolutely correct with 87 octane fuel. Keep in mind when considering compression ratio's that all fuel is going to have Ethanol in it, because the old oxygenation additive is "bad" for the environment. Ethanol is a good oxygenator, and is also hard on fuel systems set up for the old fuel. A positive side effect of the Ethanol, even though it's not much unless you're getting E-85, is that alcohol burns cooler than gasoline, so it's easier to raise your compression ratio. It also doesn't make as much power as gasoline, so it's all give and take anyway you look at it.

Bottom line is, if you happen to run 9:1 c/r, keep an eye on pinging in the engine. I highly doubt you'd have a problem though. I'd personally use 89 or higher with a 9:1 c/r.

So in other words, 8.7:1 is probably the best bet. Me, I'm going to go with 8:1, or maybe even 7.5:1, since I'll be using turbos.

If you are using a 327, using a 288 head will increase your compression to 7.5 to one. A small amount of head planing will increase that slightly.
