yeah dude, correct me if im wrong, but didnt the grand national have the l67 block (im sure it had a different name then) just with twin turbos rather than a supercharger? my lumi ltz had a l67 in it and that thing cooked. i loved the look on the face of a handfull of kids at school when the pulled up next to me in a 6-banger single exhaust stang, looking for a race and i tore them apart in my grandma car

 

Youre lumi didnt have an L67, youre lumi only had a L36 non supercharged, and the GN had a series 1 3800 Turbo, definatly a sick car.

 

naw, i had the l67, it was just in the base body... i bought it off of my uncle, his whole engine (l36) killed itself after like 6000 miles, he brought it to the dealer and they had it for almost a month, he threw a **** fit cus they had done nothing with it and he was paying out the *** for a rental. they said they had none of his engine model in stock, he asked what they and and demanded that it be put it in at no charge. after a ton of bs he finally got his way and wound up with an l67, compliments of commonwealth chevrolet and buick's no worries warrenty plan
