Dual Row timing chain & Sprockets  for the PONTIAC... 326, 250, 289, 400, 421 455 Pontiac V8 engine. Mainly Comp Cams brand or Isky or similiar top notch brand.

SPECIAL NOTE: One reason why Pontiac's are easier to work on then Chevy's....

Pontiac timing chains are a breeze to change since the balancer, and timing gears come off without the use of pullers. Also installing the timing cover is a breeze since you don't have to loosen up the oil pan [like you do on a Chevy and break the seal. Chevy balancers and timing gear are pressed on and can take quite a bit if time to remove and replace.

You can do the whole timing chain swap on a Pontiac in the time it would take to install the balancer alone on a Chevy.

NOT for 301 Pontiac.
