I guess we ain’t made no noise in a minute so figured we would bark one time lol! From finishing up the widebody kit and totally fresh paint job with a twist on Havoc, to pulling the motor back out of the Roadkill truck for a little upgrade to a fully forged 408ls stroker, to finishing up the Forced Inductions Interchiller and DSX flex fuel kit on the C8 and getting it all back together, to dialing in the fresh meat in Ol Blue and getting her ready for her DSX flex fuel setup too! We are definitely making steps but just being quiet!! And if things stay on track as they are now then we got another big move and announcement coming up soon hopefully!!🤞 💪👊🙏🤟

Some days are definitely better than others, but it’s hard to have a bad day when you get to love on these kinda units! Had to put a better throttle body on it and make a few minor adjustments to the tune. One extremely well built 1966 C10 with a 5.3 ls in it!

This Ol girl even gonna get her AC back!
