Where you can find the blue book for a 67 Chevy El Camino What if the body and interior has been redone however you are not one to know about under the hood it has a 350 engine and a 350 tranny?

You can get an estimate of the value at www.nada.com. If the vehicle has a 350 then that is not the original engine, and the value goes down. This is a classic and the value is very subjective. I would contact someone who deals in this type vehicle to find the true value. Evan a local Chevy dealer can help. This vehicle is probably worth way more than you think. I would guess from $7,000 to as high as $15,000 depending on condition. If it had the original 283, it could go as high as $20,000. Even a rough ElCamino will bring close to $5,000. You have a rare classic that was produced in low numbers, so the price is determined by what someone will pay.
