My 318 Build with questions
I'm gonna suggest cutting the heads another .020, for a total cut of .030, thin MP head gaskets, you might make 9 to 1 compression.
Yes, if he cuts the chambers down to around 56 cc and uses a .028" thick head gasket, and the pistons are down .080" in the hole with 6 cc valve reliefs, then it'll be around 8.8.
DCR would then be around 7.6 for the 256 cam installed as ground, which should work well with pump gas.
BTW OP, you can work all this out yourself. I use the Pat Kelly calculator, available as a download program online. I don't mind, but it is not any particular magic, just knowing how to derive or find the numbers to put in the 3 tabs.
- The 3rd tab is for CR (SCR and DCR), which can be run on its own for SCR.
- The 2nd tab is for intake closing angle per the chosen cam.
- It's output is used in the 1st tab to compute effective compression stroke length for the DCR option in tab 3.
