guess how much power we put down!!!
will there has to been an answer to all this, i mean the graph doesnt look like its a stroker motor, an its just a kid that owns this car, that him an his dad put together. they dont seem li ke the type that would hide this from me. an he had told me when he put the new heads on the pistons were flat an look stock. who knows maybe someone down the cars past had put a different crank. or this kids is a really dam good liar idk, i give up. i just know that the dyno isnt lieing an it made what it made with that setup,
So how did you decipher is was a 346? You said stock 80k mile short. It's bad info to come here without a graph posting numbers #1 and #2 not knowing 100% certain what it really was that was on the dyno.
this is what i was told my the owner, i never built the car, i cant see back behind the block to see if its a 5.7 or not. so im just going by what the kid had told me what the setup was on his car. all we did was the SD tune on it.
That intake didn't add 70hp. The car has 1 3/4 headers which I think would hurt something making "that much power"
If it was that easy to make that much power everyone would do it but few do. So there is either, more to the story, or someone isn't being truthful.
The OP came into this thread with little to no info. It is a good way to get people talking though.
My car dynoed 435 locked(AUTOMATIC) on a mustang dyno,so somewhere around 455-460 on a dynojet would be the comparable.My heads are not milled and im running a ported Fast 90.His numbers seem a little happy,but i bet i would be in the neighborhood of 475 if i was running through a M6 with a stock 10 bolt.

wow...serously guys. okay let me exsplain the only way i can reason with this. keep in mind im shocked to at what this setup made. but just so you know this is on a dyno jet, and was as speed density tune, not a maf tune.
now compare to another setup i did to a customers car that was a 5.7 block i know for a fact an i built myself, he has a stalled auto with a stock 10bolt 342. but he has a ls6 intake with a stock tb, stock balancer. with a fresh rebuild on a speed density tune it made 415hp.
so if this other car is a 6speed an has the same 10bolt, but has much bigger intake/tb and cut outs and underdrive pully and is also on a speed density tune. that should be close to adding up right dont you think.

Well in this thread it looks like their are about 3 real close using the same MS3 and PRC heads. Beats me! Maybe/Maybe not but track times tell the story.
In that one thread the guy does post a time with a 125 MPH trap so possibly.

wow! incredible numbers!
im not going to discredit anything here. but we are all at a lack of information on this engine. i mean, he could have higher compression with some higher octane fuel....
the numbers are great! just havent seen many people do it! just wondering...

OP, post a graph or I'm going to lock the thread. This entire discussion is nothing more than pointless hypothetical arguments about why it should or shouldn't make that a claimed amount of power and you attempting to subliminally pimp your shop and/or tuning services.
Making claims of 503rwhp out of a 346ci motor definitely demands a graph for validation as there are only a handful of stock LS short blocks in the entire world that have done that.

Certainly, if there were over 40 dyno pulls, there is a graph you can post. People just want to see things like torque at 3000 rpm, the shape of the curves, the weather correction, and whether the graph was STD or SAE. Simple stuff really. Not posting up a graph hurts the credibility of the claim.
