      I wonder what I will be seeing as soon winter is over and I get it tuned.
      My winter's project was the following:
      • M52B28 crank
      • 276° dbilas cam
      • 130mm maxpeedingrods
      • Early, catless pistons
      • Supertech valves
      • ported intake manifold and head
      • 3" all the way to the MAF (inclusive widened OEM air box)
      • late M30 MAF
      • enlarged throttle body
      • 19 pounds Ford injectors
      • OEM exhaust
      I just might have made an mistake in terms of the combustion chamber.
      In order to equalize the different chambers I mildened the edge of the squish area.

        What's the resulting compression ratio? Stack height is 0.5mm less than stock, combustion chamber larger, how about the deck height/piston to deck clearance?

          Compression ration should be in the realm of 9.5-9.7.
