Following in his father Devin’s footsteps, Kingman, Arizona’s Clint Zumwalt found a love of speed and racing cars at an early age...
He would often go to watch his father compete in sand drags, asphalt and street racing events, and eventually got behind the wheel of his first car, a 1974 El Camino that he raced with his high school friends. And, at just 18 years of age, Zumwalt was piloting a dragster that he later sold so he could work towards building himself a no-prep-style door car.
“Through high school I had the chance to help Bill Webber with his race car and also worked in his machine shop, Sureway Au tomotive and Machine,” Zumwalt told us. “This was my first job in high school.”
It wasn’t his last, though, as Zumwalt picked up a torch and started learning how to weld.
“In 2013, I started doing chassis work on other people's cars, eventually working my way up to full chassis,” Zumwalt explained. “In 2017, we built my Dad's squarebody, tube chassis ‘79 C-10, which was my first tube chassis build.”
Since the truck was essentially a family heirloom, with Zumwalt’s grandfather hav-
ing bought it new and later passing it down to his son, the pickup truck has received many makeovers through the years.
“There were many dif ferent builds with many different chassis modifi cations and engine com binations. This taught me the ins and outs of chassis tuning and fab rication,” Zumwalt said.
Since his first car was an El Camino, Clint Zumwalt decided that he wanted another one to build into his own race car. He found this ’66 locally as a pretty beat-up basket case and bought it for $1500.
A Legend in Their Own Time
Turn your LS into a legend in its own time with Trick Flow GenX® 280 HIP cylinder heads. These ultra-performance HIP’d (Hot Isostatic Pressed) castings are significantly stronger than regular heads. Fully CNC Competition
Ported 280cc intake ports deliver industry-leading airflow and Trick-Alloy™ powdered metal valve guides add durability. Manley 2.165" Severe Duty stainless intake and 1.600" Inconel Extreme Duty exhaust valves withstand extreme temperatures and big power adder performance. Trick Flow by PAC Racing dual valve springs, titanium retainers, clearance for 3/8" pushrods, .750" thick decks, 6-bolt-per-cylinder mounting, and LS3 rocker stands (assembled heads only) add the finishing touch.
Your Formula for Mega GM LS Performance!
New heads are just one part of the horsepower formula. To make it complete, you’re going to need some other components.
Track Max® Camshafts
Give your GM LS an even bigger power boost with a Track Max camshaft. Available in several hydraulic roller designs up to 230°/238° duration and .625"/.625" of lift, they are dyno proven to produce significant power increases over the entire RPM range.
Active Fuel Management and Variable Valve Timing Delete Kits
The problem: most performance camshafts don’t work on engines equipped with AFM or VVT. The solution? Ditch them with these Trick Flow delete kits! They include everything to completely remove AFM and VVT the right way, so your engine will make the power you expect with no hiccups.
R-Series Intake Manifolds for GM LS3
Trick Flow’s R-Series single-plane intake manifolds bring the simplicity of carbureted-style aspiration to the GM LS3 family.
