Nothing major except normal maintenance (oil changes/tune ups, etc.)
It could use new weather stripping.
I am a die-hard Ford truck man, but this Chevrolet is a major exception.
Grandpa's old car. He took meticulous care of it. There's no rust and all chrome and paint has held up nicely.
Original 327? engine switched out in late 80s for a 454 out of a mid-80s Winnebago motor home.
Stock 2-speed automatic transmission switched out at about the same time for a Torque-flite 3-speed.
I'm lucky to get above 10 mpg driving in this car.
Fantastic acceleration. Goes from 0-60 in about 8 seconds.
For part of the year, the El Camino sits in the garage. Every spring, I take it out on a rural, straight stretch of highway and floor it to get it back to shape. I've had it going 110 mph.
Even though it has a 454, it is fairly quiet in the city. The engine starts to really get noisy over about 70. And, at 110, I cannot hear the radio turned up full-blast.
Great old car!
Forgot one thing: low 12-second quarter mile time.
Here are some new things I learned about the El Camino over the past few months:
-the original engine was a 283, not a 327 like I said earlier
-built in the Fremont, CA plant
-the engine is a 1989 model.
