Three tubes are temporarily tack-welded to their feed pipes. Use a straightedge or piece of straight pipe to ensure they’re all level and evenly spaced. The leading pipe (on cylinder No. 1, right) is not shown, as it must be routed to clear the upper shock absorber mount. We’ll tackle it last. Ford mod motors place cylinders 5, 6, 7, and 8 on the driver side (from front to rear) and cylinders 1, 2, 3, and 4 on the passenger side (also front to rear).
