Video: Twin-Turbo 4.8L Chevelle Walk Around

Several weeks ago we showed you Don Wilhelm’s cool 1970 Chevelle, and now we’re proud to bring you this short walk around video complete with some footage of the Chevelle in action. As you’ll remember from our feature on the car, Wilhelm’s Chevelle is powered by a 4.8L truck mill that gets a little atmospheric boost from a pair of T70 turbos that rest on flipped truck exhaust manifolds. The turbos are pushing right around 5 pounds of boost, but still give this big classic Chevrolet all the extra motivation it needs.  To keep up with the air flow from the twins, Wilhelm also installed an Aeromotive A1000 fuel system and some big 80lb./hr. injectors on the little 4.8L. We like it because it’s a simple set up that makes plenty of power, and likely didn’t cost an arm and a leg to put together.

Considering that the portly Chevelle is using a TH350 trans to turn a 12-bolt with 3.08 highway gears, this thing flat out gets it down those long and flat country roads. A word to the wise though: it’s best not to adjust your GoPro cameras in front of the “State Boys.” They might get the impression that you’re up to no good in your hot-rod Chevy. Watch the video above to see what we mean.
