Build Breakdown #1
1978 Camaro Z28
Owner: @78.z28
This Z28 isn’t trying to rewrite history. It’s preserving it and turning the volume up just enough to feel alive.
Under the hood sits the original numbers-correct 350, lightly massaged for street manners, sound, and reliability..
Engine & Performance
Stock GM 350 small block
COMP Cams XE268H hydraulic flat tappet cam
COMP Cams matched valve springs, retainers, and locks
Cloyes double roller timing set, properly degreed
Edelbrock Performer RPM intake manifold
Holley 650 CFM vacuum secondary carburetor, street-tuned
Stock-style mechanical fuel pump with new fuel lines
GM HEI distributor
MSD performance ignition module and coil
AC Delco plugs and fresh plug wires
Long-tube headers with 1 5/8-inch primaries
This combo keeps vacuum healthy, idle slightly lopey, and drivability exactly where a street car should be.
Exhaust
Custom 2.5-inch dual exhaust, headers back
H-pipe crossover for torque and smoother tone
Electric exhaust cutouts mounted under the car
Dual-path system:
Valves closed: sound routes through OEM-style turbo mufflers for a mellow, factory cruise
Valves open: unrestricted exhaust, classic small-block bark
You can drive it quietly through town or let it speak when the road opens up.
Cosmetic
Completely original exterior and interior
Factory paint, trim, and body lines preserved
Stock 15-inch Z28 Rally wheels if you’re wondering
Interior
This interior is pure late-70s GM, untouched and beautifully preserved.
Factory camel/tan interior throughout
Original high-back bucket seats with factory cloth inserts
Original door panels, dash pad, and center console
Factory automatic shifter and original steering wheel
No cracks, no aftermarket pieces, no modern replacements
The materials, textures, and colors are exactly what you’d expect stepping into a Z28 in 1978. It has that warm, time-capsule feel where nothing looks restored, just carefully kept. The kind of interior you don’t see anymore because most cars this age were either redone or worn out.
Details That Matter
This is where the car really flexes its originality.
Original GM ignition keys still in use
Factory Camaro Z28 key fob, period-correct and perfectly aged
One of those small details that instantly tells you this car hasn’t been messed with
And on the back of the car:
Original dealer sticker still intact and untouched
No peeling, no reproduction, no replacement. The exact sticker that was on the car when it left the lot is still there today. That’s the kind of detail collectors and real enthusiasts notice immediately.
Owners Future Plans?
Big block swap with EFI
Or a modern LS swap topped with a ProCharger
Two very different paths. Two very different personalities.
