Cool, thanks. It makes sense that it would be the injected
(750hp) motor he'd use. (I have one of the older single turbo
motors; Marino said that the big motor has dual bolt bearin caps,
mine's stock).

The 199 plus turbo junk has got to be a lot lighter than a V8
for the same HP level.

It also calls into question just how many engines were built.
Breedlove ran the big Navarro six in October 68; the Indy 500
was that next May, 1969, the last time car #50 ran, with the
"same" motor. Plenty of time for a teardown, but maybe Navarro
used a fresh motor that May. Then there'd be at least two of
that particular motor.

Where'd they all go...
