5.0 Willie

It's called a GNX. Good swap. The Buick 3.8 is one of the most stout motors ever made. I have a Grand Prix GTP (Buick 3.8 S/Cd) and the bottom ends will take SERIOUS power. More then a Subie motor could ever hope on stock internals. ZZP was running 8 second passes on a stock L26/32 (newer 3.8 variation) long block.

When I can get around a scanner I'll upload my slip. Stock 05 LGT sedan 8/21/10 RT -.018 60' 1.996 330' .000 1/8 9.131 1/8 mph 75.29 1/4 14.374@93.66

Damn start the work already, I'm eager to show everyone I know in the 3800 community.

The GM 3.8 is an amazing motor. If you need a gen III M90 I'm parting out my car. I've also got a gen V IC core, headers, volt booster, tb heat shield and lots of other stuff. I blew the 4t65ehd out of my 98 GTP and am sicking of replacing that terrible transmission so bought my LGT.
