Hi from Australia I dont own a Grand Prix but I am A Pontiac fan in general and a fan of the L67 , This is my 98 VS L67 Holden statesman its pretty much stock other than a boost increase and corvette servo ,also it has the standard features of ABS ,IRS
Also I own A 1957 pontiac it runs a 455 pontiac turbo350 and recently had a 9inch conversion ,but it is enjoying an extended vacation due to a shonky engine builder
So I look forward to reading up on some tips for the L67 and seeing some nice Grand Prixs cheers
