back to he comments before about the rod length ..... it does matter because the better the ratio the means your motor works better together and you know what shit you have in your motor.... it also means more compression and hp's

ill be using a gt40 or explorer and gt40 heads and an e cam is whats planned also gonna run spray and it is still efi...... im getting a cobra intake with the heads but i think the gt40 will work just as well and have a little bit more of a sleeper look to the non mustang peeps. and ya im sure your heads will flow plenty of air lol but everybody uses those im sure they work very well i just want to be a little different and i got a deal on my heads soooo.... why not !

It's not as easy as that. You could build a 306 that is nice an docile on the street, or it could be an animal, same goes for the other combos. Street manners has more to with the heads, cam and intake. Generally, you will get the same HP level, but at a lower RPM, with more cubes.

someone asked if you could put 289 heads on a 347. they are on mine. the engine was in my buddys car and was bad as hell!! the heads were decked and when my uncle was alive he ported the heads and put bigger valves in them they flowed awsome. i put 3" exhaust on it with race mufflers. still needing to time it but having a hard time.

There is a lot of good reading on here. I think there should be some updated stroker articles. After spending a fair share of time on the phone and internet with techs from AFR, Edelbrock, Scat, and Ford Racing getting educated on the right setup for me. I brought all of this info (oil loss with the 347, durability of piston rings, skirts, etc...) to the table for discussion and problem solving. As of May of 2010 this is what I have been schooled on. According to the mentioned companies Edelbrock has designed the best head to manifold setup/combo for the 302/351W block. AFR did compare their heads to edelbrock's, but on a much higher performance level (drag/stock car level). After an hour on the phone with edelbrock it was decided that the performer rpm 5.0 II combined with a cylinder head from the Edelbrock XT (Xtreme Series) line. The choice on head depends on what I want out of the car, so I am not 100% on my needs yet, but they assured me any of them from this line would be just right for a 347. The tech from edelbrock also suggested a 42lb injector. Once I asked about cams he directed me to Ford Racing, or Crane Cams. I spoke with a tech from both companies. I am still waiting on an email response from Crane to include info and options on cams. FR suggested a X or a Z303, but again it is all depending on my application. As for the Stroker kit, I spent a great deal of time on the phone with an engineer from scat. Really nice guy, and it seemed like he had all day to answer my questions. As for the oil loss answer, they designed a "Gutter Ring" (his terminology not mine) that sits just above the wrist pin so that oil is retained more so than before. I asked him "Does it stop the oil seeping?" He responded, "No, you can expect to lose approx. 1/2-3/4 of a quart every 3-4k miles". This is substantially better than the old designs that did lose more oil. I then asked about the skirts as well as the possibility of this stroke upgrade lessening the lifespan of the engine. He when into the whole long story of how application, treatment, and abuse plays a very large role in the life of an engine (i.e. boosting, racing, etc...). The bottom line is (from his perspective) if you run a Hyper dish forged piston with Chrome Alloy rings keeping the compression at approx 64-70cc along with their 302-347 stroker kit the engine will make a "Solid, dependable, and enjoyable daily driver". He took into consideration the information I acquired from the other companies.
Over all I have found "My Build", but it took lots of questions, research, and willingness to have an open mind. I learned that the most expensive is not only the best and that it is all "Proper application and combination of parts". My fear of building a ticking time bomb has perished and swayed my decision between the 331 and the 347 stroker kits. I hope this info can be helpful to any of you out there. I am not a professional in the area of auto mechanics, that is why I called all the companies I did. I say this so that members out there with questions to my build will keep many of their suggestions and comments at bay as I will not be able to answer them efficiently. Hope my efforts may benefit you, Jesse |

There is a lot of crap in this post. 347s don't burn oil, period. They are no different than any other engine. I've owned more of them than you do underwear. Never burned a drop of oil. If someone at Scat actually told you that crap, it was a sales pitch. As far as Edelbrock, AFR, Ford Racing and Scat "educating you" on the right set up......I have to pick this apart so someone doesn't read your post and become misinformed. When you want advice on the right combination, you call an engine builder not a manufacturer or salesman. Some of this crap I don't even know whether to believe it was a real conversation or not. If any of it actually took place, then these are good reasons to never call tech support at any of these companies. Why does the Edelbrock tech recomend a 42lb injector in a 347 when 30lb injectors would be plenty for the combination listed? And then the he recomends the competition for a camshaft? I doubt it. Fyi, I would not use a Ford Racing cam. I'd probably use the stock cam before I use any of the xyzpdqabc Ford Racing cams. The best head and manifold are relative to the combination. What is best for one combination might not be the best for the next combination. Every company will tell you they have the best cylinder heads, cams, intakes, etc. The people that will have answers that are worth anything are not the manufacturers, but the people that actually have used the parts and dynoed or ran down the track and have some real world numbers.

I only took the info I was provided and posted it. That is all. You can call it crap all day and it doesn't matter. If you would like to question my post PM me and I will be happy to give you the names of the people I spoke to and the numbers along with extensions. I did not speak with any build shops, only with two owners of stock car racing teams. I will admit they do not have as many engines as I "have underwear", but that is nor here or there.
You seem to be really upset here and being that you have so may posts and I have so very few I can see the type of person you are by the comment you left. I have no reason to provide false information in this site, for some insecure reason you feel I do. I will no longer be returning to this site and I can anticipate two things: You will provide a comment explaining your joy for someone no longer on here providing "false" information, and second a moderator will remove this post. By the way I never said 347s "burn" oil. Only that the location of the wrist pin allowed for oil loss. So, please, see a professional, get on some type of psychotropic medication, read members posts s-l-o-w-e-r, and use some tact when you reply.
