Valvoline has been in the oil game for over 140 years. To honor this oil legacy, they have teamed up with two of the biggest names in NASCAR, Jimmie Johnson and Dale Earnhardt Jr. The pair will compete in a truck build off, reinventing two classified Chevy performance trucks.

Valvoline is inviting enthusiasts to guess what Johnson and Earnhardt Jr. are building. If you guess correctly you will be entered into the contest to win a classic muscle truck of your own. What suspension do you think the trucks will have? How about wheels? With they be red and black, silver and white, flamed out?

All you have to do is head over to and build a truck in their virtual garage. Also, follow Valvoline and Truckin Magazine on Facebook and Twitter for clues about the builds - with the hashtags #TeamJimmie or #TeamDaleJr.

Truckin Magazine will also have a sneak peek of the trucks next month and we will make sure you know everything there is to know about them, after the contest ends of course.
