I thought it had .065" more bore? What's DOD?

I know 4" is a pretty popular crank size. I figured 4.100", 4.125", and 4.250 were too. So what makes Callies better than Eagle? Those 2 are the brands I'm considering as I can't afford Lunati. I have yet to decide, so I'd like to know.
I'll double check/search and see what the bore is. I could of swore I read 4.065".
Could you elaborate more on displacement on demand? Still means nothing to me. Thanks.

DOD is an oil pressure activated, deactivation of lifters, that effectively turns the v8 into a 4 cylinder engine resulting in a 7% increase in fuel economy.
Does anyone know what extra work needs to be done when not using DOD in a shortblock build up?

Not trying to drum up business here, but email me at bnutter@wiseco.com I'll help if I can, because it's definitely not up to a "vote". -Brian Nutter

So I sure hope builders can get 525/525 today from a 422.

I'm in the middle of reading all 14 pages of the SDPC L92 thread. First BG-SDPC says straight out that 4.1 is out of the question b/c the liners are too short. A page later he states that the liners are exactly as deep as those on the LS2, and that it is a piston ring placement issue.

Eagle just started selling a 4.25" stroke crank that they made specifically for the Warhawk blocks. I know that the rod/stroke ratio would be bad, but does anybody think that one of these would fit in a LS2/L92?

What the heck is up with this thread? I keep seeing it get bumped up with new postings, but when I view the thread, it still has the same last post from Randy WS6. If you're looking at the threads just browsing the section, you'll see the last post was made at 10:41 pm yesterday, but when you actually go into the thread and view it, it says the last post was made on 10/27/06.
