Complete bolt in frames built to race specifications and set up with off the shelf racing components are now available for late 60s muscle cars and early pickups. These are the answer to getting high level handling and performance from your early muscle car.
Let's face it, the early Camaros and Mustangs, Chevelles and Novas were great looking and fast in a straight line but what happens when you try to take them around a turn? Body flex and old engineering combined to produce a less than pleasant experience. Now, along with reproduction bodies for early cars you can get complete bolt in frames with the stiffness and components to deliver modern handling. In the case of unibody cars like the Camaro, it converts them to full frame eliminating the twist and flex modern engines can easily cause from horsepower and torque far above what the stock engines produced.
Jeff Schwartz of Schwartz Extreme Performance, now offers a line of frames for 1964-1972 GM A-Body Chevelle, Malibu, GTO, Lemans, Tempest, Cutlass, 442, Skylark GS, 1967-1970 Mustang, 1962-1967 Nova, 1967-1969 Camaro, (converts unibody car to full frame) 1947-1954 Chevy, GMC pickup and 1935 Ford. The frames are designed to bolt up to the stock body mount locations.
If you think you would like to build a pro-touring "g machine" this is the place to start. With any amount of power available from various crate engine suppliers plus reproduction bodies, there is almost no limit to the possible muscle car based high performance street machines you can build up. You don't need to dig around looking for an early car with enough pieces to rebuild, you just put together a new car.
Prices for these frames run from $2495 for a bare frame to a complete roller with steering rack, brakes, and rotors for about $12,900. When you consider the time, effort and money you would put into trying to put a frame under a car yourself compared to getting one of these brand new precision, jig built frames, they look like a great deal.
