My buddy Ron claims to have a '79 115 to hang on the Baja.
(I shouldn't tell you this, because it's posed to be classified top secret. But the 115 came off a CVX 16 that he's almost finished restoring. Gonna have a 150 HO Etec on her now.)
Regardless. The Baja'll run 55 with a 90. Oughta do at least that with a 115? For sale cheap!
