@smithsdieselperformance: After many grueling hours and 6 melted pistons, we thought we had our 6.4 Burnout truck ready to rip at @Southern Ohio Smoke Show … we were wrong. Can you guess what failed? Full engine rebuild and disasterious burnout on YouTube now!! Stay tuned for next weeks video to see all our Smoke Show content and what we did to bring her back for one last rip!! • { #burnoutchallenge #burnoutpit #truckshow #enginerebuild #64powerstroke }
