Need help calculating CR. Here is the setup.
6.0 Iron Block 408
Stroke: 4.00
Bore: 4.030
Piston Dish: -23.6cc
Head CC: 72cc
GM 6.0 MLS head gasket crushed thickness: ?
I need some help figureing this out. I did a search and read some of the threads but could not figure out exactly what to do. If there is any other info. needed to calculate this please ask and I will post it up.
Also I need the part number for the GM MLS 6.0 head gasket. I did a search and the part #12569365 came up but it is not a good number according to GM Parts Direct.
TIA
