The 302 is the sweet spot for a stock-appearing, reliable Bronco. Leave the points alone or swap to Pertronix — it's the single best $90 you'll spend on the ignition.
Ford's 302 Windsor (5.0L) became available in the Bronco in 1969 and was the dominant engine through 1977. Early versions used a 2-bbl Autolite 2100; later trucks got the 2150. Output was approximately 170 hp gross (pre-1971 SAE gross rating), which translates to roughly 130–140 hp net by modern measurement.
The 302 is well-suited to trail driving at stock gearing with 31–33" tires. It starts to feel strained above 35" tires, especially with a 4.11 or taller rear gear.
**Common issues to address:**
**Oil leaks:** The 302 uses a rope rear main seal. Replace it with a rubber conversion kit (Fel-Pro BS 40596) if you're doing a major service. Front oil pan gasket leaks are common; use RTV sealant on the corners.
