This car used to be a 305 carb car, auto. I recently turned it into a 5 speed, built a 355 with the l98 alum heads, roller rockers, bored .060 over, shorty headers, true dual exhaust, mallory breakerless dist, super coil, dual rev lim ignition box, performer rpm cam and bow tie intake. I installed a 4.30 gear in the rear and am using 275/60/15 tires on the back. I am hoping to run it at the track soon and see what it will do in the 1/8 mile.
