OUSCI Preview- Curt Hill's '72 Chevy C5 Blazer
Today's preview of the 2012 OPTIMA Ultimate Street Car Invitational, presented by Royal Purple and KN, focuses on Curt Hill's '72 Chevrolet C5 Blazer. The '67-72 era of GM trucks is gaining in popularity, but most of the focus has been on the pickup bodies. Hill went a slightly different route with this C5 Blazer, but the modifications found in many of the pro-touring pickups of that era are also found on Hill's truck.
Hill runs Hill's Rod Custom, so the C5 Blazer really represents the best of his company's craftsmanship. Curt feels the Blazer will really shine in the Lingenfelter Performance Design Challenge, as the frame of the Blazer has been extensively-modified to correct all the shortcomings of the factory design. The truck's stance has obviously been lowered, but it has not been bagged. Rather, there are extensive modifications to the cross members and inner fender wells, to allow it to sit as low as it does on a coil-over suspension system and still fit 255-series rubber up front on 20-inch Intro wheels and 275-series tires in the back. There is also a custom-fabricated four-link in the rear.
The Blazer has more than 1,000 miles on it since the completion of the build, so Curt doesn't anticipate any issues completing the Detroit Speed Engineering/JRI Shocks Road Rally. Hill also feels the truck will perform well in the Wilwood Disc Brakes Speed Stop Challenge, as it has 13-inch rotors on all four corners, powered by a Wilwood master cylinder.
Curt is really looking forward to competing in the RideTech Autocross, although he only competed in his first autocross a few weeks ago. That will leave him deficient in the experience department, compared to many of his competitors, but Curt's first autocross went well and he is confident in his ability, as well as that of his truck.
The Blazer may do better stretching it's legs on the big track in the BFGoodrich Hot Lap Challenge. Power comes from small block Dart, displacing 406 cubic inches. The combination includes Brodix heads, MSD ignition and a Holley carb that breathes through a KN filter and results in a stout 495 horsepower and 500 lb.-ft. of torque.
Curt tells us he won't be afraid to push his truck to it's limits and he's going to need to, as the 4,200-pound curb weight is going to make it one of the heavier vehicles in the competition. You can see Hill's truck in action, but you need to buy a ticket and they're going fast. Buy your 2012 OPTIMA Ultimate Street Car Invitational tickets today!
