Well, you could say the same thing about a 7.3 as a race engine compared to the old 6.9 then. We could follow that line of reasoning on down the line comparing old engines to new engines.
And how is the design different other than the HEUI injection different from a 6.9 to a 7.3? NONE!
And how is the design different other than the HEUI injection different from a 6.9 to a 7.3? NONE!
Let's see, the 7.3s are bored another .110 and I do believe they use 1/2" bolts, also they are balanced differently then the 6.9s. Not much in the grand scheme of things, but they are differences in the design, which is what you were asking. Also are we talking IDI or DI 7.3s; turbocharged or non-turbocharged?
I know the OP has a turbocharged 7.3 and it's DI, you got quite a lot of difference for getup and go then you do for the 6.9 stock v. stock. I know Banks makes a turbo kit for the 6.9, but you still have some differences there.
Well other than the bore size the IDI 6.9 and 7.3 are the same. When for went to the IDI the injection system went from a mechanical injector pump to a HUEI system. And although none of the IDI and DI parts are interchangable they are a very similar design.
As for the 6.0 to a 7.3
6.0 has 4 valves per cyl vs 7.3 has 2
6.0 has splayed rod bolts the 7.3 does not
6.0 has a block girdle built right into the block the 7.3 uses bearing caps
6.0 uses a VGT while the 7.3 uses a standard turbo
I am not saying the 6.0 is not newer and there for has more modern technology but it is far from the 7.3 in likeness. The only things they have in common are a V8 ,HEUI injection, and built by international
well sorry i wasn't able to respond any earlier i was out drilling with the army. so alright i believe i got it now, back pressure = enemy. there for i reckon i'll be gett'n a straight pipe with a 6 inch. tip for now as it seems to be pretty cheap, then eventually get a turbo back exhaust once some more funds come in. thanks for all yalls helps. i appreciate it.
a little off hand, but when lining up a 7.3, against a 6.0. who's likely to win ? both are automatics. the 7.3 would have the edge juice/attitude, and the 6.0 would have a diablo sport chip in it. who's more likely to win?

It depends on a few more variables then if they are automatics. Depends on the tunes that they are running, the driver, how much weight each truck, gearing, tires, general setup of the truck, how far the race is etc.
If going just by hp/tq numbers that's one thing, but sometimes a good driver can make up for some shortcomings.

6.0 is 325hp while a auto 7.3 is only 250hp. You do the math

I've seen less hp vehicles beat vehicles with more hp, given a few variables(which aren't out of the realm of possibility with the two vehicles mentioned) going just the right way a 7.3 can win.
Oh by the way, just to illustrate the point, my stock hp numbers at the rear wheels were less then 300 hp due to how my truck is configured. Flywheel numbers(which you quoted) are off already, how off they are depends on how each truck is configured. Yes, the 7.3 is also going to be off the 250 that you quoted, but how far off depends on some variables. Also, tuning plays a part since they are both autos. Depending how if the truck likes the tranny programming of(I would assume the race tune would be the ones used) those off the shelf tuners will determine if the 6.0 does well despite the higher hp advantage. Mine did not like the higher hp tunes of the BullyDog(not Diablo I know, but still off the shelf tuning) and just about anyone could beat me with that irratic shifting of the bullydog. Now given enough time roadway, it would eventually work itself out, but if it was a short burst, no it wouldn't do good.
Using hp numbers can give you a good baseline(better if you use rear wheel numbers if you have them), but that alone doesn't make it for certain and this is still assuming that there is nothing wrong with the trucks otherwise. Even something as a small injector leak can cause 40% loss of hp(and that is fairly common to happen on 6.0 injectors).
I've seen people with just a tuner run 5" exhaust systems because they are under the false impression that in that particular case, bigger is better and they would actually lose low end grunt because they weren't flowing enough fuel/air. That would also affect how things come out in the end. Lot of variables here.
hhmmm. wow i was unaware that the 6.0 housed that much more hp than the 7.3. the 6.0 i'm refering to racing is a 4 door long bed, and such is the 7.3. both of them F350. i rode in this guys truck before and he stepped on it, however i noticed it was slow to get up and go as i've felt in the majority of 6.0's but once it shifted gears that's when it really began hauling. the 7.3 on the other hand gets up and goes a whole lot quicker from the start, but once the gear shifts it doesn't climb speeds as rapidly as teh 6.0. i'm guessing because of the differences in RPM's. i was hoping to see an increase here once i install the chip, but really don't know what to expect. do any of yall run the edge juice with attitude ? and if so there any tips for really using it for it's potential. to include safety warnings and other things you might want to recomend that i be aware of. this would be my first tuner so i'd like to know as much about it, and troubleshooting and what not before i install this puppy and start playing with it. last thing i'd want to do is melt the heads on this truck. thanks for all yalls help.
Do your self a favor and dont get the EDGE. It ups cyl pressures too much and advances the timing out of the safe range. And w the PMRs your truck most likely has, you will window the block
i saw you explained the PRMS on the previous post could you please expand a little more on this? is there a way to fix it ? and when yous ay window the block what does that mean ? and i kinda sord of already purchased the chip and incab monitor but have yet to install it... :S i had heard good reviews on it, but also heard some bad in it too. so i reckon i dun made a mistake gett'n it ? i paid out 624 for it. pretty pricy mistake
PMR= Powdered metal rods= fine for stock and junk for mods
Window the block= break a rod and punch a hole in the side of the block w the broken connecting rod. NOT GOOD
yeah, you could change the rods w 94-00 powerstroke rods. But yeah, have to pull the engine to do so. You can get a reconditioned set of forged rods for like $480
how much you think labor would come out to replace those rods ? sounds like that'd be a little to much for me to do on my own. where can i find the build date of my engine on my 01. hopefully if it was an early o1, there might be the possibilty that it'll have forged rods. is there a way i can visually check for the type of rods i have ?
Your are looking at close to 2k in labor.
And the build date has nothing to do if it has PMRs or not. Next time you do an oil change, look up the drain plug and look at the rod bolts. If they are 12pt head bolts they are forged. If they are 6pt nuts they are pmr rods
