If you find some, let me know. One year motor = not much available. I would however love to be corrected on this matter ( for the sake of my '54 Customline).
ive been to hell and back just trying to find a fuel pump and other odds and ends. ive seen maybe two intakes for sale for this motor and they are all turbo expensive. if anyone knows please chime in.
It depends on two things (not counting available $$$): one, which version of the 239 you have; two, what you are looking for. There are two separate versions of the 239. One is known as the "Cleveland" 239, and is identical in general design to all later Y blocks. The other is known as the "Dearborn" 239 and has some differences; for instance the cam journals are 1/8" larger, it has a 13-tooth distributor gear (all other Y blocks use a 14-tooth gear), the fuel pump is different, and a few other things. I've written about this in a number of other posts so I'll skip the rest of the details for the moment. The "Dearborn" camshaft is no longer made as a cam blank and it is hard to find. Some time back, Chris Nielson had some NOS blanks if I recall correctly; http://www.nielsoncams.com/ . John Mummert might have a source as well : http://www.ford-y-block.com/yblockpage.htm Putting the cam & fuel pump aside, most other Y block parts will bolt on to the Dearborn 239, like intakes, headers, valve covers, etc., and of course the Cleveland 239 is compatible with most everything. Later distributors will work on the Dearborn with some additional effort. I highly recommend using an aftermarket distributor or a '57-up distributor, and there's been some recent posts about this also. The last thing to consider is that there are three basic sizes of intake ports. As I am too lazy to type all this over again, I'm going to quote from an older post of mine regarding the cylinder head intake ports & intake manifolds: "So far as the intake goes…it’s complicated. There are three sizes of intake ports for the Y block, more or less. The early “small” ones of the 239 & 256, the “medium” ones, which are by far the most common, which some people call the ’55-’56 heads; and the “large” ones of some ’57-’59 heads such as the ECZ-G. Heads made after ’59 are basically “mediums”. You can, in fact, do SOME intake mixing & matching, with care. However, the large port intakes, such as the 3x2 Edelbrock FM357 or Edelbrock 357, will almost never seal to a small port head. (I say “almost” because some people claim to have done it… However, early intakes are sometimes found on eBay, and Offy will still make the early small port 3x2 intake. DMARV here on the H.A.M.B. can get one as he’s an Offy dealer. You would not want to use it on the “large” port heads, although it will probably seal to the “medium” heads. A “medium” intake will generally seal to the early heads, with care, although you sometimes have to search for a different brand of gasket… 3x2 intakes: Edelbrock FM357 or 357 (lg), FM355 (med.); Offy 2726 (sm.), 3199 (med.), 3199-7 (lg- I think); Fenton DM424 (sm- I think), DM425 (med.- I think); Edmunds (sm.); Weiand (dunno). It might be a good idea to ask any seller to measure the ports prior to bidding." Hope that helps a bit...if you are not certain which 239 you have, post your block casting number.
You can still find Yblock 3X2 and aluminum 4bb on ebay but you have to look hard. Other option is a log set up and here is a link. http://victorylibrary.com/mopar/log-c.htm
thanks u for all the advice so far. i will post my block casting numbers tomorrow. as far as speed equipment im just looking for a cam, intake, and some other dress up item i cannot find. its a 54 customline by the way. also, on a related note, does anyone know what manifold will fit to make true duals? i converted my car to 3 speed floor and have freed up the room for the driver side pipe. no one seems to know what would fit. thanks again.
the mr gasket one from autozone. it wasnt my first choice but my linkage snapped so i had to cut the floor.
lots of good information...thank you,so can i use a 2726 offy on a 1963 292ci with it's stock heads? is there any benefits ?
Well...depends on your particular definition of benefits. There's no doubt that a 3x2 intake setup, all dressed up, looks cool as hell. They can also be made to run without hesitation, bogging, fouling plugs, and so forth. In my experience, there are not too many guys that have the knowledge or patience to properly tune them...so the owner either pays a professional, suffers with a snotty-running engine, or throws it on the shelf. I would venture to guess that there are more dusty 3x2 manifolds sitting on garage shelves than are on actual engines. Only you can decide where you fall into all of this and what you are willing to do or to pay. If you decide to have a professional set them up for you, there are some good guys here who have reliable track records and can help. it won't be particularly cheap, but quality never is. If by benefit, you mean "add horsepower"...well, again, it depends. To be blunt, most older aftermarket manifolds don't flow worth a shit, or make good power....or, they are "peaky". There are a few exceptions. If your existing carb/intake are in poor shape, you'll see a large improvement from a properly setup 3x2. If your existing stuff works...you'll see an improvement, but probably not the "tear your head off" difference you might have been expecting. The best production manifold out there for Y blocks, power wise, currently is the single four barrel unit sold by John Mummert. Of the vintage stuff, probably the Edelbrock 3x2 357/FM357. But others can be made to work.
Just got done building a 239 for a 54 i'm doing, try ownes salvage on here, got some stuff from them for it, but they not that good a motor, think about a 292 or 312
