It’s an L67 which was used in:
Chevy Monte Carlo
Buick Regal
Pontiac Grand Prix
Chevy Impala
Olds Riviera
:weak:
To the OP. Very good numbers. And a sign that Pittspeed doesn’t hate on any specific type of car for no reason. Even a Buick Regal W body is getting props cus he’s making power out of it!
