I recently purchased a 91 GT all stock except exhaust. Im looking the Holley intake, heads and cam combo for $2199. The car doesnt burn any oil and it runs fine, i was thinking if the motor ever went bad I could just get another 302 and put the holley sytem on the new engine. They advertise this system to produces 350HP with the proper fuel system, does that sound pretty accurate? Any other combos or ideas welcomed.
