HTM On The Water
We chronicled the building of the Challenger 600 EFI engine over the course of two months and now the boat is ready to get out on the water for testing. We headed out to Lake Elsinore in Southern California (one of the few lakes without a speed limit) and gave the boat a whirl. With the help of Paul Pfaff Racing Engine’s Gordon Jennings we had a good day on the water.
OVER AND UNDER
Our old 350 Chevy-powered ’47 International was running a three-speed 350 Turbo trans with 4.11 gears, which, as you know, is not a great combination for this type of highway cruising. It is fine, however, for those who absolutely love in-town, short-?distance, stop-and-go cruising, as it does prove great low-speed throttle response. On the highway, however, it spins up the engine and uses more fuel. We decided that after having our low-speed fun, we were using too much fuel and weren’t comfortable listening to the whine of the small block as we approached 70 mph. It was time to make a change. We looked around for a number of answers and talked to many classic truck owners who had either installed a new set of gears, an overdrive trans or a Gear Vendors overdrive/underdrive unit. We figured that the new 700R4 trans best fit our application budgetwise, although future plans may call for a Gear Vendors unit, as it represents the best of both worlds. But we first wanted to start with a newer, more modern trans.
KING OF THE ROAD
“Carroll Shelby has pulled the trick of the year. He’s combined Ford’s new drag champion 428 Cobra Jet engine with his complete road car, the Cobra G.T.500. Result? Cobra G.T.500KR…King of the Road.” Those words accompanied the full-page advertisements for the mid-year introduction of the ’68 Shelby Cobra G.T.500KR. The new model replaced the early ’68 G.T.500 and its more docile 428 V-8 engine.

The Alien
This ’67 Nova Is Back in Black
When firefighter Joe Chavez of Irving, Texas, was a senior in high school, he grew up in Santa Rosa, New Mexico, and drove a ’66 Chevrolet Nova. “I had a lot of fun with that car. I called it the “Alien,” and everybody in town knew whose car it was,” Chavez says. Unfortunately, when Chavez relocated to the Dallas/Ft. Worth area in 1985, he couldn’t afford to take his prized Nova along with him. As the years went by, he found himself regretting the decision more and more.

The Search Begins
“In 1990, the hunt was officially on. My wife, Michelle (who also owns a ’67 Nova of her own), and I made numerous road trips to Florida, Tennessee, Pennsylvania, Louisiana and back home to New Mexico before I found what I was looking for,” Chavez says. Ironically, Chavez found his dream car in—of all places—Santa Rosa, New Mexico! “After purchasing a ’67 Nova SS fix-’er-upper in my hometown, I took the car over to Bozo’s Garage, where my half-brother Ernie Ortega works on street rods, to have some work done on it,” he says.
Bodywork and Paint Restoration
Once at Bozo’s, Ortega and owner Bozo Cordova replaced the ’67’s rear quarter panels and a small section of the Nova’s floor pan. They also hammered out all of the dents and repainted the ’67 black. “I also had them install a 400cid GM small block out of a wrecked Monte Carlo. Once I got the car back to Texas, I cleaned up the factory black vinyl interior, replacing the items which needed replacing. I then installed a set of 15-inch Cragar S/S wheels, just like I had in high school, and got the windows tinted. Finally, I had a presentable Nova, and started entering the car in car shows,” Chavez says.
Rear Suspension and Driveline Specs
As for technical information, the SS features a 3.73:1-geared GM 10-bolt live rear axle riding on a pair of mono-leaf Nova rear springs, Energy Suspension polyurethane suspension bushings, Air Lift airbags and Monroe shocks by Rick’s Independent Car Kare, located in Irving, Texas.
Front Suspension and Wheels
The front suspension on the ’67 was also completely rebuilt back to stock by the folks at Rick’s and features a pair of 2-inch dropped Easy Street front spindles, Energy Suspension polyurethane suspension bushings, Air Lift airbags and Monroe shocks. The aforementioned wheels and tires on the “Alien” measure 17×7 inches in front and 20×8 inches on the rear, and they roll on a set of P215/45xR17-inch front and P255/35×20-inch rear Federal radial rubber.
Engine Rebuild and Performance Upgrades
Chavez has since rebuilt the 400cid small block, and the engine now features a set of 0.030-inch overbore Speed Pro forged aluminum pistons, Crane cam and kit, a pair of GM double-hump cylinder heads with Crane Cams valvetrain hardware and Mickey Thompson valve covers, Holley Street Dominator intake and 650cfm Edelbrock 4-bbl carburetor, and a chromeplated twin-snorkel Nova SS air cleaner. The ignition is the factory GM HEI unit while the exhaust comes from Hedman Hedders and Flowmaster. Backing all of this up is the factory original Muncie four-speed transmission using a Hays clutch and pressure plate activated by a Hurst linkage.
Final Touches and Show Car Status
“In 2003, I decided to completely repaint the Nova. After looking around, I finally settled on painters Kirk and Jason Tyre. Kirk and Jason did a fine job spraying the Nova in DuPont Raven Black,” he says.
Awards and Recognition
Other upgrades include Chevrolet Bow Tie halogen headlights and Year One exterior trim. Chavez’s ’67 has won 100 car show trophies and awards at events like the Super Chevy Show, the Dallas Autorama and the Ft. Worth Rod & Custom Car Show. Needless to say, the “Alien” is back!
