This for a an LS1 application. In an earlier thread I asked about tire size with a 2D and as I understand it, it's all about the reverse loading on the R&P under deceleration. So my question is which combination R&P is the strongest, the 4.13 or the 5.14 or something else? I can get aproximately the same overall ratios in each gear with the 4.13 as I can with the 5.14 by using the appropriate gear sets available for the 2D.
So if I want to build a 2D that will hold up to a 35" tire, gear ratios aside, I would think that there is a gear set and R&P combination that would be optimum for strength.
Any thoughts on this?

build it around the 5.14 R&P
I am going from a 4.63 to the 5.14 to have a little more meat on each gear in the stack.

build it around the 5.14 R&P
Okay, thanks but why? What makes that R&P stronger than the other? Could you give me a quick overview. Ring diameter vs. pinion, my understanding would have the 4.13 with the larger pinion (stronger?) given the fixed ring size.
As onanysunday said, the gear stacks would also come into play. So larger pinion equals less strength in the gear stack for similar overall ratios?
If there is a source for this kind of information I'd be glad to do my own research.
Thanks,
Mike

It is all in relation to a circle and how many teeth can be put on a diameter.
It is a trade off this is why I say 1st-4th are percentage gears and what % you will be using them.
In ring & pinion it is a 100% gear running all the time.
the tooth physical size is also a consideration as well as the shaft and ring gear width to help with deflection.
To do some info searching I like to use http://auto.howstuffworks.com and a overall Google search.
