Sort of a vague rule it seems. I guess if you read it one way, if an OEM made (or maybe just sold under their part number) the block, then the spacing is OEM, unless you modify it. I was thinking that NHRA finally put a limit on Pro Stock at either 4.9" (I think that's correct) or 5.0".
It remains to be seen whether the R07 makes substantially more power, or is just more durable and easier to work with, and has a small HP increase. I think if it had a great deal more HP potential, and NASCAR could see it, they'd have never let it in. Remember how much trouble GM had getting the SB 2 and SB 2.2 stuff in?
Of course, I'm not real convinced that the current bunch running NASCAR is exactly the sharpest knife in the drawer when it comes to doing anything but screwing up, and trying to squeeze another dollar out of their gullible spectators.
