Granatelli Rolls Again

— Santa Monica, Calif. —This is a stock

Plymouth engine? According to USAC

Indy rules, it is, even though you

couldn’t exactly buy it from your

dealer. The block is from a 318-cu-in
engine (to stay within race rules for

unblown stocks); head and valves are

adapted from a 340-cu-in engine (also

Chrysler’s), and the fuel-injection

system will be something else again.

Biggest surprise at a recent STP COLORFLOW

■
press conference was a new body PRESSURE COMPENSATED
design, the “Super Wedge”. The PRESSURE COMPEJ NTROL & CHECK VALVE

stress-carrying shell within is taken PLOW CONTROL &
almost directly from last year’s turbine MODEL TPC

cars. Externally, it looks (well, almost)

like the equally pretty rendering that adjust

made the media rounds a littler earlier

(March 3, 1969 DESIGN NEWS, p. 16).
Aerodynamically, though, the body

shape differs substantially. Seen from

topside, the cockpit fairing begins

almost as a needle point, tapering in a

straight, continuous wedge back to
the (replaceable) spoiler edge. The

main body shell has backswept air

intakes in the shape of low-silhouette,

unusually wide rectangles (looking

more like wingroot intakes on a Comet).
Body width goes to Indy limits, partly

covering the front wheels.

It’s a mean-looking monster, and

although there had been no time for

wind-tunnel tests as yet, somehow the

shape looks very right. At least two
complete cars, and several spare

engines, should be ready in time for

the qualifying runs.
