CRANE "4/7 SWAP" SFO CAMSHAFTS
Crane’s most recent SFO introductions include cast iron cores, small base circle steel cores, and steel 55mm cam bearing cores for the small block Chevy. Also added to the availabilities are cast iron cores for big block Chevys, steel billet cores with 60mm or 2.125” cam bearings for Chrysler’s 426 Hemi, and steel cores for the 429-460 c.i.d. Ford.
By changing the firing order from the stock 1-8-4-3-6-5-7-2 (Chevy and Chrysler) to the alternate 1-8-7-3-6-5-4-2 (or 1-5-4-8-6-3-7-2 for the Ford) is has been demonstrated to obtain nominal power gains due to improved fuel distribution (especially in open plenum intake manifolds) and “smooth out” the torque curve.

Retrotek Boss EFI still Available
The BossEFI simply replaces the carburetor, (no new manifold or fuel rails required) providing a clean muscular appearance. It is identical in all critical dimensions to a 4150 and features four high-pressure port-style injectors placed strategically above the throttle plates, providing optimum fuel atomization and power output. In direct back-to-back comparisons to port EFI RetroTek’s BossEFI made equal or more power.
RetroTek’s billet throttle body is not the only unique part of its system. The Stage II Engine Management System has an “adaptive learning” feature that self-tunes as you drive – no laptop or tuning skills required. It takes its information from a wideband O2 sensor and control module, with no welding is necessary for the sensor installation, thanks to an innovative clamp that attaches to the exhaust. Systems include all wiring, sensors and instructions. Installation takes about six hours.

'86-’93 5.0L MUSTANG FUEL SYSTEM TUBING
The 1986-‘93 5.0L Fox Body Mustangs have emerged today as an affordable and stylish performance car for both street and strip. Over the years, the Mustang experts at CLASSIC TUBE have created OE style pre-bent replacement tubing for these popular vehicles, and they now have replacements for the 5/16-inch FUEL LINE, the 1/4-inch VAPOR LINE and the 1/4-inch RETURN LINE.
These Mustang fuel system lines are available in pre-bent stainless steel or OE steel with the correct size end fittings. CLASSIC TUBE’s lines are exact duplicates of the original parts, and are your best insurance against fuel system failure. Over time, original rubber fuel lines can harden, develop cracks and also begin to leak, not a good thing! As with all CLASSIC TUBE products, these lines have been pressure tested and conform to stringent D.O.T. specifications. To find out more about these and all of CLASSIC TUBE’s fuel, vacuum, choke, transmission, hydraulic and brake products, log on at www.classictube.com.
