Quote: 100 passes on a rebuild not even maybe and when ours is runnin good we usually take out a valve spring every third pass Who's valve springs are you running? Are you breaking them or just replacing them. Every 3 passes is a lose lose deal.

Of course if unlimited budget you can have a billet block made anyway you want. I toyed with the idea of using a CNC motorsports BB Ferd block drilled for the Hemi 99 heads. The valvetrain geometry would suck though. They make those blocks up to 11" deck iirc.
