In 1973 Chevrolet replaced the SS (Super Sport) logo on their Chevelle with an S-3 option -- without ever admitting what the 3rd S meant. Regardless the S-3 was combined with the Laguna name to build a polyurethane front ended coupe and that was supposed to help the NASCAR teams be more competitive...but the story doesn't end here. Apparently, if you knew the right COPO (Central Office Production Order) codes you could order the S-3 Laguna nose on an El Camino. Find this 1975 Chevrolet El Camino Laguna S3 here on eBay bidding for $565 reserve-not-met with $16,500 buy-it-now located in Stillwater, OK.
The El Camino with a Laguna nose is very strange -- it almost looks like what Chrysler would have built if they decided to make a Cordoba-camino. However, if you want a unique looking El Camino to stand out in the seat of Utes at the next car show -- this would do it.
Propelling this thing forward is an entire drivetrain swap (engine/trans) from a 1995 Z28 Camaro -- which should be an LT1 5.7 liter V8 good for 275 horsepower and 325 ft-lbs of torque (this one has an LT4 cam and should be good for a few more) mated to a 4L60-E automatic transmission.
