Modern motors deliver modern reliability and modern emissions standards. With clever tuning, air intake and exhaust modification, you can deliver serious horsepower. To this end RRS has developed all the parts that make Modular V8 conversions into early Falcons, Mustangs. Fairlanes, Cyclones, Mavericks, and many Fords possible. Modular or Crate motors require a wide engine bay, wider than many of the early Fords had so you will need custom made engine mounts, shock tower notching, headers, exchange wiring harness, coil over struts, fuel tank pumps, speed sensors. RRS worked with some of Australia and New Zealand's leading car builders to put together these kits which we supply in single units or as a package deal. Please contact RRS sales to get pricing on the next step of turning your classic Ford into an ultra reliable, daily driver or track day dominator. With an RRS Shotgun modular V8 conversion, you can have it all — a legend car you can drive everyday.
