Printed camshaft specification table for Ford V8 engines showing lift, duration, RPM range and grind notes.
Part of 1992-1996 Ford Bronco Manual Pages
This document is a cropped scan of a camshaft specification table (apparently from an aftermarket camshaft catalog, likely Melling given the 'MC' part number prefix) covering Ford V8 engines from 1962-91 in 221, 255, 260, 289, and 302 cubic inch displacements, except the 1982-85 302 H.O. and 302 C.I. engines with hydraulic roller lifters. The firing order is listed as 1-5-4-2-6-3-7-8. Two camshaft part numbers are fully visible: MC4120, a hydraulic cam with duration figures of 190/202 and 258/271, lift of .413/.437, lobe centers 106/114, a 1000-4000 RPM operating range, smooth idle, 900 (likely idle RPM or vacuum-related spec), and application code B, noted for good low-end torque and towing; and MC1734, a hydraulic cam with 204/214 and 280/290 duration, .448/.472 lift, 108/116 centers, 1500-4000 RPM range, smooth idle, codes B and G, noted for strong low-end torque, towing, and good mileage. A third row is cut off at the bottom. Column headers are not visible in the scan, so column meanings are inferred from typical cam spec layouts.
