123 ignition system

1.6 punto block, tipo cylinder head, 78.4mm stilo crankshaft, scat forged rods, used low compression wosner pistons. Various other small parts. Cast pistons are available from Andrea Vencl or Simeone on Facebook. Mine is making 136whp on rolling road. That's at 11:1 compression ratio. I would build for pump gas this time
 
Regarding the "low compression Wossner pistons". What bore size and what compression are they with a stock size crank?
 
They have a special 27.5 compression height for 8.5:1 c/r so with a stock 1.6 crank it probably wouldn't start. 86.5 maybe. 87 mm bore. Need to check it. Mine is 87.5 with forged Iapel pistons.
