On the Street
Out of our five challenge cars, this was the most enjoyable to hit the streets with. That's not a knock on the other cars, as they were right there with the Hotchkis Chevelle, but this one had me ready to steal the car and head for Mexico when no one was looking. The ZZ383/Tremec TKO600 five-speed combo gave the car plenty of motivation (in fact, this was the only manual transmission equipped car in this year's field) and the Centerforce clutch was just right for the street. The only complaint, a minor one for sure, was the shifter handle on the Tremec was a tad short. As I have about six inches more height than the car's owner, so I'm sure it fits him just right.

Driving along with John Hotchkis riding shotgun, I was impressed by the responsiveness of the suspension, but it didn't give the Chevelle that buckboard, rough ride feel like a lot of other suspensions will. Admittedly, this car tied for the longest wheelbase (115 inches) of our five challenge entries, which helps, but it felt so smooth and so good you could see driving this Chevelle every day. Even going over a rough railroad crossing, the '65 remained stable and straight, with no teeth-rattling sensations transmitted through the suspension to the passenger compartment. The Scat ProCar seats were form fitting but comfortable, while the thick, ringed Grant steering wheel allowed for the perfect amount of feel and control.

Even though the car has a roll bar, it didn't affect the comfort of the cabin. The clutch had great feel without being a burden in traffic, and the 17-inch diameter wheels left plenty of room for tire so the ride quality was further enhanced beyond the suspension.

The steering was still the factory GM design, just upgraded with a quicker ratio power box. It wasn't heavy, it wasn't light, but spot-on in the middle of perfect. The manual brakes (Wilwood master cylinder combined with Baer calipers) were surprisingly light, not requiring an enormous amount of effort to actuate, and had plenty of feel and control. You could lightly lay into the brakes for light stopping or hit them hard for a panic stop with no difficulties. They really showed what a correctly set up manual brake system has to offer.

Overall the Hotchkis Chevelle was just flat out awesome. Smooth roads, rough roads, traffic, clear lanes, didn't matter. Everything was so well balanced and had the right amount of feel, doing a cross country trip in this classic would be fun. Even without air conditioning!
