Timeless Muscle Magazine Features Tony's GTO!
Tony brought his '69 GTO project to Speedtech for a complete full tilt build. What he got in the end was one of the most wicked street driven GTO's in the western states, worthy of multiple feature articles and stealing the spotlight wherever he takes it. Most recently it was featured by Timeless Muscle Magazine who were seriously impressed by it.
From TMM, "Tony Madonia owned a Pontiac Lemans when he was in high school, but he always wanted to bring a Pontiac GTO home. After owning a few different Pro Touring cars, he finally got his hands on his GTO in September of 2013. The plan was to build a high-end Pro Touring car from the GTO. After speaking with Blake at Speedtech Performance and going back and forth for almost a year, Tony decided it was time to pull the trigger on a brand new A-Body Extreme chassis. From there, a whole new kind of machine was born."
"At the top, an ultra aggressive Comp Cams hydraulic roller cam with 247/251 .624”/.624” lift and 114 LSA gives it some major get up and go. The Trick Flow Specialities cylinder heads were built up by Sullivan Performance, who did the rest of the work on the engine, with Trick Flow aluminum intake and exhaust valves, LS3 with trunion upgrade 1.7 rocker arms. Topping the engine is a Whipple supercharger that runs 12psi and has a 2.9-liter front inlet.... The exhaust flows into Speedtech headers from the engine, and into a 3” Stainless Works exhaust system with Stainless Works mufflers. When he needs a little more kick and a lot more growl, Tony employs his Quick Time Performance electronic exhaust cutout."
"Back to the chassis work, the Speedtech Extreme A-Body chassis is the biggest overhaul of the whole car. Since it’s a custom chassis, the builders could hand pick the components that would help Tony get the ride characteristics he wanted out of the GTO. The chassis has been loaded up with the best suspension parts out there to make it ride like a supercar, instead of an old school muscle car. ...The GTO also has a Speedtech torque arm to round out the suspension, while a Sweet dual power steering rack gives Tony a lot more control while on the road or track."
"It’s amazing how the automotive aftermarket has made it possible for a 50 year old car to drive like a modern performance machine” -Tony Madonia
