The bottom end is the foundation you've gotta build this right or those super race pieces will be junk if a cheeped out bottom end lets go.
That said let's start with the question of how will this engine be used?
Then what are you expecting for power and RPM? I'd say there's a lot of potential for big numbers!
What block is being used and vital dimensions like have the cylinders been bore and if so how much? Include whether its been decked and how much? Align bored mains and any other engineering data that sounds like it could be important?
