Sprint Identification for 1968
Short answer: A real 1968 Sprint has single exhaust but a dual-outlet exhaust manifold (a Y-pipe joins the two outlets into one header pipe), so single exhaust is correct. Confirm it by engine code ZD with a VIN matching the car — that’s the correct Sprint block. Most other Sprint parts could be added to a base 1-bbl car, so verify the block and get PHS documentation.
Other 1968 Sprint features:
- Larger crankshaft harmonic balancer
- 4-bbl Q-jet #7028261 (M/T) and 4-bbl intake manifold; chrome-lid air cleaner
- Special dual-outlet exhaust manifold
- 4-bbl-only cylinder head with dual valve springs and a smaller chamber (higher compression)
- Larger-lift, longer-duration cam; distributor recurved for more advance
- “Sprint” badges on the rocker-panel moldings
- 3.55 rear axle ratio; heavy-duty rod bearings (only visible on disassembly)
