All the gasses exit through hooker super-competition headers (2 1/8" primaries), then through a dual 2 1/2" equalized flomaster exhaust system. The stock 350 3-speed was completely rebuilt and treated with a shift kit. The interior was completely restored from the floorpans to the headliner with variouse year one products. The exterior was mostly clean, so we decided to wait a while for any paint. Next up for this car, I would like to cram a 455 in there with some new rims and paint, but only my budget can decide when that all comes(and it doesn't look like anytime soon).
