Catalytic converters and ZDDP

Cool stuff!

I'm really keen to get some case vacuum going, thinking my drysump will a tad

Nice work Steve! Another nice cat to use for more stockish engines is the converter from an early to mid 80's Saab 900. It is a monlithic/ low resistance cat....under about 12" long and has three bolt flange that uses swivel type slip joints for alignment on each end (when you get the factory cat which is still available at most private Saab shops)...and is right at 2' to 2.25" inlet and outlet. The aftermarket versions are weld in. Ray
