Fitment and installation requirements

Specify the actual engine deck height, Windsor or Yates cylinder heads, power-steering arrangement, chassis and induction. No A/C compatibility. The 1985–1993 reference describes the accessory arrangement rather than guaranteed direct fit to every stock vehicle. Fuel-system upgrades, carburetor/EFI equipment and custom tuning are separate. Carbureted builds require a suitable blow-through Holley 4150-style or similar carburetor and adequate hood clearance.

Head and finish choices

Each listed head is included at the family price. F-series heads use straight-cut gears; helical gears are not offered. Satin is standard, black adds $295 and polished adds $450. Intercooler capacity ratings describe the core, not guaranteed engine output. The native variant price includes the chosen kit and supercharger finish. Optional accessories are selected separately.
