    i hear it comes with titanium connecting rods, a double row timing chain and a manual cam chain tensioner to get rid of that pesky, reliable, automatic hydraulic unit.

    I guess I don't see it ... yes, more is better and we all like speed, but it looks like there may a FEW ways to get to 80+ mph this year, WITHOUT going into the long block, so for me, this is not an interesting option. More boost, more fuel, 3 blade impellers, sounds like a better way to get to 80 for me ...

    Absolutely. One of the major benefits of boost is being able to compensate for inefficiencies in terms of head flow, etc. Sure better head flow will make more power if all other parameters are equal, but I'd rather adjust timing, fuel, and increase boost than tear into the short or long block.

    1700 cc ???? that works out to a 106.7mm bore size. I was concerned boring my engine to 101.6 (4 inch). I don`t believe there`s enough room in the block for this conversion
