My Roadrunner started as a 90% stock car. Over the years I have gone through the motor (top end only), 833 four speed, sure grip 8 3/4 diff., interior, and dash/gauges. What a journey but I know every nut and bolt. It now runs Aero heads (2.14I x 1.81E), purple cam 484/284, Dynomax headers with 3" flowmaster 40's. It breathes through a Edelbrock Performer with a 750 Holley carb. Power runs through a pistol grip 833 4 speed to a 3:23 sure grip 8 3/4. Custom dash/gauges, B5 Blue with centerline wheels. Manual steering and drum brakes. Lots of Go with little Wooo.
