Default 318 Poly Help

If you're running a 318 Poly, here's a helpful site:
The Polyspherical Engine Association
http://www.geocities.com/polyman64/

I know a lot about 'em, and can help answer questions. I also post a lot at:

The 318 Poly Yahoo Group:
http://autos.groups.yahoo.com/group/318poly/

And this 318 Poly message Board::
http://www.diamondbackengines.com/fo...board,6.0.html

Let me know if I can help! Also, I just updated the Poly Business Directory at the Polyspherical Engine Association so folks can find what they're looking for.

By the way, who has a Poly on here?

Although they say displacement is everything, you can get one of these polys over 400 CID!

Your buddy won't be able to break that crank - it's forged!

Hi, I just joined your COOL SITE as66fury3toy. I hope I'm in the right area to ask this question. Can or will someone please tell me or show me the type of 4 barrel carb that might have sat on top of a'66 318 Poly cast iron 4barrelintake? I've acquired an intake and would like to find thefactory type carb to install on it.

It was a Carter, I believe - a 500 CFM Edelbrock should do the trick. They bought Carter's casting stuff and started making them (with obvious improvements) under the Edelbrock name years ago. You're probably looking nor no more than a 500 CFM carb - maybe a downjetted 600 CFM one.

I have a 66 Coronet with the Poly 318. Mine has only 2 bolts thru the center portion of the valve covers to mount them. All the parts stores are giving me valve cover gaskets with holes for 5 mounting bolts. Am I going to have to make my own or use silicone or does someone have a part number for the correct ones. Maybe you use the 5 hole ones as is and ignore the extra holes ????

A engines like the '57 - '62 318 Polys have 3-bolt valve covers. A engines like the '62 - '66 (and '67 in Canada only) 318 Polys use 2-bolt valve covers.

LA 318s ('67+ - basically poked & stroked 273s) have the 5-bolt valve covers.

The valve cover gaskets you need are available from NAPA, Fel-Pro brand, no less, and the listing on them should say something about the years "'57 - '66", as all 318 Polys, 2-bolt or 3-bolt valve covers, use the same valve cover gaskets.

Seriously - all the stuff you need can be bought at NAPA.

By the way, you should check out the Polyspherical Engine Association site for more info:
http://www.geocities.com/polyman64/

Also, check out the 318 Poly Yahoo Group (there's a LOT of us on there):
http://autos.groups.yahoo.com/group/318poly/

And the 318 Poly Forum:
http://www.diamondbackengines.com/fo...board,6.0.html

That should cover all your bases, and get you about any information you want - all for the asking. Hit us up - we even know where to get high-performance parts (in fact, there's a listing at the Polyspherical Engine Association site).

Thanks I got your email and ordered to correct parts. Id also like some custom valve covers, either aluminum or chrome steel and having no luck. Herbs Parts lists them, but no longer carries them. Anyone...new or nice used ? I may end up just painting mine with crinkle finish like on Hemis.
