I-beam vs. H-beam rods?

I-beam vs. H-beam rods? Ok...after my post about doing stock rods in my future engine, enough people made the "is it worth the risk" statment that I'm NOT going to risk it (especcially since I found out that Callies makes a 4" stroke crank for $1,500 that I could go with (427CI 
) and thus WOULD need to upgrade anyways (longer ratio rod)...
here is where I'm at...
I'm looking at doing 500-550rwhp MAX (all motor and or with a little spray) and 6500RPM MAX....
so with that in mind, I don't think I need some "super strong space age rod"....just something that will do the job...
1st) what is the difference (strenght/ussage wise) between I-beam and H-beam?
2nd) I found a number of rods, all 6.125" with floating pin:
A) Crower I-beam Sportsman Rod = $435
B) Eagle 4340 Forged H-Beam Rods = $479
C) Lunati Pro-Mod I-beam Rod = $700
D) Lunati Pro Billet Super Light I-beam Rod = $900
$900 is really the limit that I can see spending on rods for this engine (again...550rwhp and 6500RPM MAX)...
Which would be the "best" all things considered? Is there something that would do better that I missed? Remember this is a budget build up.
thanks

Re: I-beam vs. H-beam rods? I wonder if there is a difference between a H and an I?? I could kinda see how there could be, but does it matter? so do you think its looks like the letter looks? I have never heard of any problems with any after market rods.... So pick one that more people have.
BTW where did you find this crank?

Re: I-beam vs. H-beam rods? An H-beam rod is best suited for forced induction motors where there is a compressive load on the rod. An I beam rod is usually used for N/A motors.

Re: I-beam vs. H-beam rods?
hey it says 1650!! thought you said it was 1500 
thanks!
thanks! close enough.....once it gets over $1000
I don't worry about $150...its still more than I have... I know Jegs has Eagle rods for about $600.....but I will be looking around to find the cheapest price before I buy....
(I just keep finding more and more ways to saving money on this project
....anyone know where I can get a resleeved block for less than $2000 from MTI 
)

Re: I-beam vs. H-beam rods? Perhaps 2 or so years ago I looked into the same Rod shopping questions.
Many people had very good things to say about the Lunati Pro-Mod rods. Some ok reviews of others, but nothing got the "value" nod like the Pro-Mods.
I ended up myself going with Olivers super-duty stuff for far more money than I should have spent.

Re: I-beam vs. H-beam rods? Is the Crower Sportster rod junk or is it much better than a stock rod; the narrative I read does not describe it as a forged piece????

Check out pages 150-151 in the Crower catalog.
For the weight they are pretty dam good rods. For classes with a 600g rod weight they are good parts. They are around 630-640g rods for a LS1, which is a bit lighter than the Eagle.
