hey gregg...... 

is this going to be 56 mm big bore?  forgot to ask.

to be clear, my previous comment was comparing the aftermarket dual trans big bore jug to the proto quad.

even though the blow down duration on the dual jug was only 25..... from what i found, the time-areas for blow down were out of proportion when comparing with the other ports.  because of the too high exh roof, the blow down area was very large.

low and wide trans maybe??

wishful thinking:  thick barrel flange and chamber;  thick intake floor and exh roof;  low and high comp piston options;  unfinished as cast exh and intake ports.
