This is our '55 Chevy big back window 3100 pickup. It is powered by a ZZ4 crate engine with a Turbo 350 transmission. It has a Mustang II front suspension which lowered the front end 6". The rear end has a TCI leaf spring kit which lowers the rear by 4". We smoothed the bumpers, firewall and dash. The windows were changed to one piece power windows with a kit from Brothers. The gauges are a billet insert also from Brothers.
