@PornstaR16L other common terms for the conversion kit are "Toilet Bowl" and "Popper" exhausts. This engine is still legal and somewhat competitive in the the BSH class in APBA. They are also run in vintage races. I myself am finishing building one and plan on having a video of breaking it in.

Everyone hates me due to I have extra stuff but i continually look for motors all the time. I grew up running the kiekhaefer and the seahorse motors.... so I must hoard them. LMAO

@cpgixxer The mid section was dubbed "the thumper". Mark 20H was used for B stock classes. This mid was used in the B modified class. I ran this for years and still have 2. Then retired them when OMC burst on the scene and I swapped to Yamato 20SSH/ C class

@PornstaR16L yup, has the popper midsection which is also "race".

None of you know what you are talking about. This is a Mark 20H with a quicksilver lower unit (tuned port exhaust). Stock this motor was a race motor. "H" meaning hydro lower unit and it came from the factory with being the 20H. Was the only motor to come with green and gold.
