PISTON & CONNECTING ROD
DESCRIPTION
PISTONS
The piston (Fig. 87) is constructed of aluminum
and is gravity cast, free floating design. The piston
incorporates a centrally located high swirl combus-
tion bowl, and utilizes a "keystone" style top com-
pression ring (Fig. 88), and a "Tapered Face"
intermediate ring (Fig. 88), for superior cylinder wall
scraping. Piston cooling nozzles cool the piston and
pin with engine oil supplied by the crankshaft main
journals. High horsepower pistons are gallery cooled
and utilize J-jet piston cooling nozzles.
