It is full steel. All stock from the outside, including fender opening moldings and the rocker molding for '67. It is over 3300 lbs w/o driver. I also installed Dodge Viper bucket seats for support and boy do they fit nice and look Good as well. I would post some pix however this is a new computer and I have not uploaded my pix from the old junk yet, sorry. Cam is a crane, I have installed 1.6 indy rockers to increase the lift. It is advertised as a 575 lift cam. [.383 lobe lift.] Ignition is MSD digital 6 [no advance in the distributor] 34 degrees timing. Start retard is in the Digital 6 so cranking is no issue. Converter is an 8" Turbo Action which stalls an honest 4800. I do street drive this often, not daily but weekends and cruise nights. It is a pleasure to drive. I have owned this car since 1978. It is an original 383 S car. [BH29H] vin. Any other questions I can answer feel free to ask.
