Caps are machined with dowel location diameters to suit our BD Main Studs and with lateral lands for use with parallel location blocks (i.e. Cast Iron Twin Cam & FVC 120E & BD 711M)
The crank bearing journal is rough machined only ready for line boring.
These caps are not legal on FiA Lotus Twin Cam Blocks running to Appendix K
