Real Good at Doin' Stuff

2022 WORLD CUP CHAMPIONSHIP

LEADING CLEETUS TO VICTORY

While Cleetus McFarland has certainly enjoyed some success behind the wheel of his cars, and does a great job tuning most of them, when the new engine went into the El Camino they call Mullett, he called in some reinforcements. It was time to call in Pete Harrell.

SICK WEEK 2023

"To clock those 6-second pass, Gustafsson turned to Harrell Engine and Dyno for a 540 cubic inch big block Chevrolet, and a Performance close-ratio Turbo 400 transmission with a Greg Slack converter to pass the power." -Sick The Magazine

SUPER STREET CHAMP!

Bigun wins at 2023 sick week

"A week and a half ago we didn’t have a running motor. The guys at Harrell Engine & Dyno pulled off the impossible getting this badass motor together with part’s showing up just in time. The tune up we got off the dyno is what we ran all week. Pete is a amazing tuner and I appreciate everything he does." -Eric Yost(Bigun)
