This Buick Grand National has been swapped with a Duramax. The main forum topic on the car states it does a 1/8 mile drag in 8.258 secs @ 84.81mph. Jalopnik’s article asks why would a person do such a swap while also linking to the much debated article “truth about diesels“. If the creator is after taking a challenge and making something different then I agree with some commenters, why not?
