Slant 6 Aluminum Performance Head

Turbo them, they'll eat rod bearings sooner than later, nitrous...bent rods....high rpm oil pump gear goes out.... nylon distributor drive gear.

Disagree.
Have had a turbo 170 slant since 1979, never ate a rod bearing. street/strip car 10-12 lbs boost
Sprayed a 170 a 225 HP and never hurt a rod. Pistons, yes
170 slant at 7,000 rpm never lost a oil pump or gear.
Nothing wrong with the nylon dist gear, very little load on it.
Most problems I have had is head gaskets, pistons/rings. Cause: detonation from a bad tuneup.
