I'm looking to spend no more than 2500$ on a preassembled 347 stroker short block. I've been looking in the 5.0mag and they got DSS bullet for 2000$ or the the pro bullet for 2500$. In summit they got the ford 347stroker short block for 2400$. What do you think is the best thing to go with? Thanks
good 347 stroker short block

I suggest going with a 347 assembly that has the slightly shorter 5.315" rods (vs. 5.400") ...
You will eliminate the oil control ring and wrist pin bore intersecting each other this way. Plus the compression height of the piston will be a little taller ... more meat on the top of the piston.
CHP is the only company I KNOW OF that sells them.
I think the manufacturer of the rods and pistons is Probe
DSS however makes a better main cap girdle ... it is constructed of aluminum which is much better at absorbing engine vibrations than steel.
Anyhow, I know homeboy above (Grn92LX) has an engine built with the 5.315 rods in it.
I have a 331 from DSS with the 5.315 rods in it.

Yes I do have the 5.315" probe rods, I wanted the 5.4" but Rick called me and told me they were on a long ass back order so I went with the 5.315". I use the probe ultra light I beams. I would rather have had the 5.4" though.
I am going through Rick 91GT for my 347, sent the check today. His prices are very good. I would go through him, he also gave some good advise. He's not just some salesman that's going to try to advise you to get something just because it cost more money.
I am also going for the Scat 9000 kit with the 5.315 rods and probe forged pistons. I also got the Spec Billet Steel Flywheel and the Poineer balancer, as well as having everything balanced.

Agreed, Rick is awesome! I've talked to him about my future motor. He'll be building my 347 when I'm ready. His prices are insanely fair. Much lower than you are looking at.

Wait a minute ... we all know this debate has been pounded to death, but I have to ask you.
Are you in essence saying that Probe, DSS and others only went through the designing, tooling and manufacture of the 5.315 rod for no legitimate reason???
Do you feel it is based solely on some urban myth???
I am just saying, if assembled correctly neither will use more oil then any other combo.
Probe came out with the 5.315" rod. I like them since it allows the use of a 1.175" CH piston (same as a 327/331) for a little more meat. The 5.4" uses a 1.09" CH piston. The extra meat is nice for a power adder car...
The oil burning myth is a internet myth and hype, same goes for a lot of the information thrown around on the boards.

As an engine builder I say to you 
It's not an internet myth ... the 5.4" consumes more oil.
There are a number of advantages to the 5.3" .. not only designed for p/a cars
Assembling an engine incorrectly is poor workmanship regardless of rod length.
If you are saying using a 5.4 with an offset pin bore piston then I would definitely agree with you ... but centered, the engine will consume more as I've heard of it first hand ...
A friend with a long rod 347 in his '87 coupe consumes more than normal with only 20K adult miles on the build ... and also an ex-coworker has one in his 2wd F150 and same deal with similar mileage. They were both broke in properly and not run hard.
CHP and others know that the 347 will consume oil when housed with the 5.4's. Are you saying they are f.o.s.?

I have to stand by my statement. I have assembled both senarios and have yet to see any noticable difference in oil control on both combo's, same goes for power.
Do I build more 5.315" stuff yes...but the engines I assemble along with many other that use the 5.4" will work just fine with no issues.
The extra deck thickness was only one of my points, and for a Power Adder car it is a consideration depending on the intended use of the combo.
Would I tell Mark O'neal (Owner of Probe) that he is FOS, sure and he'd laugh. Actually he's a helluva guy that I have known for a few years now, quite knowledgable.

Unfortuantely things change and some people are stuck reading magazines (READ: Advetisements) and what xyz friend did.
On your same logical basis are the companies *significantly* larger than CHP and DSS with significantly more R&D and engineering behind them FOS? Is there a reason that they maufacture, sell and use these "oil burning" kits yet seem to be able to have spotless names in the industry and sell millions of dollars of parts? I mean Ford, Scat, Eagle, and JE are just a few of the small ones that come to mind that use pin intersecting products.
5.315" 347 strokers were made to solve a 10 year old problem and are now 100% marketing. Yup, you got it, marketing. Pin intersection was solved with a dimpled oil rail support in the '90's. There are thousands and thousands of kits that haven't had problems since (think much larger than SBF... SBC, BBC, BBF, the entire peformance market.)
With 50 different places for you to buy your stroker kit how are we going to differentiate our product? Why do you think it's the same companies with 2 page add spreads getting the stories about them? Do you honestly think it's coincidence that the article you read about DSS's kits being the best thing to sliced bread is published in the same magazine they pay $10k+/month?
The facts are:
- Pin intersection does not = oil consumption!
The 5.315" kit offers a "taller" piston, which can sometimes be benficial for power adder applications. If you're not running a power adder guess what you just did? You have a taller piston, more material = more weight. You put the weight at the end of the lever... Why?
I have no preference either way, we're a *large* distributor for Probe(CHP), Scat, Eagle and most names in the performance engine arena but I'm not going to scare my customers into buying a myth.

Good points here. Most performance engines do burn some oil, but concern is when it gets to the point the oil starts to clogg/gum up things.

First off, please don't mistake me for some 18 yo kid with his first set of keys.
A lot of what you said is true ... but
How can you tell a salesman is lying ..... when his mouth is moving
Ya, I know that's old.
You sell for Scat right? ....
Does Scat make a 5.3 rod?
What is the weight difference between a 5.3 and 5.4 347 piston ... negligible. Keeping the block in one piece and head gaskets intact is more of a concern for a track guru than oil consumption.
The fact of ad spreads and dollars is not in dispute at all.
I am quite aware of the almighty dollar and back scratching.
I work around salesmen all day
However, friend xyz are not idiots either. You insult my intelligence by making the statement, but I realise you don't know me from Adam either.
Anyhow ... you're right.
Good Luck.
This is the problem with forums... You make a post that's incorrect, someone makes a post to correct yours and all of a sudden it's personal.
It's NOT.
You're right, I don't know you from Adam. What I do know is stroker kits and this business. What I do know is that a lot of people blame problems on things that aren't the source of their problem.
If you took things as personal then I'm sorry, they aren't intended to be. I have absolutely no interest in getting into a personal match with anyone I don't know, specifically over a forum.
