What's the potential for boring and/or stroking the 55k M113 block? I know Havoc tried this with VRP and Vadim but is there potential for this or is there just no more room. By the way that company Vath or Vathe or something offer a 5.8 M113. Renntech also did a 6.0 litre http://www.motortrend.com/roadtests/...0/viewall.html This was an NA though.

I'm having my block bored after the sleeves are installed. Waiting to hear what the maximum bore size for the sleeve is to decide what we want to go with. I'd rather leave a few cubic inches on the table in trade for more strenth. I was advised against the stroker option plus the cost would be so much higher either having a crank reground and the rods will be shorter plus all the unknowns with possibly needing to clearance the block.

Aren't our motors already stroked 5 liter blocks? How much more room can there be for the pistons to travel?
