what was original in the car? it was probably a 350 sb but may have been a 402 bb. you can check the vin or look for the build sheet, usually under the back seat, under the carpet, or on top of the gas tank. We found ours on top of the gas tank.
I found out it originally had a sb but a 402bb was later added.
Here's the info I received about the car
To make it safe and reliable:
rebuild passenger side brake caliper
replace shocks
replace anything in the suspension and some miscellaneous that is rubber
front end alignment
balance wheels
new battery
diagnose and fix instrument panel lighting
replace window felts and rubbers around doors
fan for defrost and blowing air is not working
To make it more presentable:
body work and paint from rust around the rear wheel wells, rear window and just general deterioration of the paint over the years; the hood is almost completely back to primer
replace interior overhead
re-cover rear and front seats
new carpet
cover or replace dash
replace sun visors
needs a new stereo system and gauges
rear side windows need repaired mechanisms that make them go up and down; right now they are in the up position, but if they get rolled down, they ain't comin' back up too easily
Optional fixes:
gas gauge works, but on about a 25% scale (1/4 full means its full)
12 bolt posi rear-end;
rebuild the engine; it consumes oil
inside of trunk is pretty rusty
Done in the last four years
steering wheel
plugs, plug wires, points, condensor, coil, starter motor (very high end after market one), water pump, rear-view mirror and tires
brakes are good , however, they are four wheel drum brakes
