Clois,

The 445FE bore is based on a 390 block, so it's usually a .030" or .040" over 390...which is a 4.080" or 4.090" bore size.

I run Melling HV pumps.

The Probes are available in two flavors, dished (18cc) or flat top (4cc). With the typical 72-74cc chamber sizes from Edelbrock and a zero deck setup, you're looking at around 10-11.5:1 SCR. I can also do Diamond pistons and put the SCR wherever you need it to be.
