When we talked to Dave Z, we said ‘we need the works’. We’ve tested our designs over and over, and it’s backed by our hands-on experience with some of the fastest NMRA racers and Mustangs in the country, in each class.” “What shows through is more than just the quality of the welds. “Our parts are built for racers, by racers,” explained Zimmerman, Team Z’s founder, and the “Z” in Team Z. Simply put - these components are not built by a chop shop welding team in China. You’ll know that racers know and trust Team Z to help them get the maximum performance on track at their horsepower level. If you’re a fan of Mustang Drag Racing, you know Team Z. Follow along as we not only install a complete Team Z system front and rear – but also give you some key insider setup times from Dave Z. To give our Fox some hook – we went to one of the top suspension drag doctors in the country: Dave Zimmerman’s Team Z Motorsports. And as we’ve found out – we always choose to. It was time to build 666 a suspension system that could easily run low 10s but also give us a foundation to go faster if we choose to. You’ll remember our Project 666 from the last few months of updates - a 1986 coupe that will do a little dirty work on the street but mainly thrive on the track. That being said, the factory Fox components are flimsy, non-adjustable, and in need of some geometry changes to produce optimum 60-foot times. ![]() Heck, as we all know, highly modified Mustangs with stock-type suspension have even eclipsed the 6-second mark at over 200 mph. Light weight – and with a suspension system that leads itself to quickly “HOOK” on the 1320, the Fox is as good as it gets. Mechanical camshaft of 290 degrees of duration & 0.The Fox-Body Ford Mustang is one of the most popular chassis choices in history for drag racing. Heads just like the Boss 302 with canted-valves Canted-valves (2.19" intake and 1.71" exhaust)Ĭompression chamber of 66-67 cc (compared to the Boss 302's of 57-60 cc)įorged steel rods - shot-peened & magnafluxed with heavy duty 3/8" bolts and nuts Compression was around 9.2 with open chamber heads and a Forged flat top piston with a single valve relief. It had solid lifters, and most of the other associated parts. It actually had a larger lift cam the 71 version, although the duration was less. but the lawyers made them change the name. This engine is almost identical to a 71 R code Boss 351, and was even refered to as the Boss 351 in Ford literature. engine was a seperate engine with VIN engine code "R". Lower compression heads and hydraulic cam. For practically any application, the Ford 351 Cleveland is the performance choice with plenty of horse power and torque. Even today the 351 is an engine of choice. The four barrel was rated at 266 horsepower. The two barrel version was rated at 160 horsepower. the following year, 1973, was the 4 barrel Cleveland 351's last year. The solid lifter cam had a little less duration (275 degrees) and more lift (0.491"). The heads were open chamber instead of the semi-hemispherical. All the heavy duty parts were kept but the compression went to 9.2:1. In 1972 the Cobra Jet motor was renamed HO for high output. The compression was 9.0:1 in both motors. The motor was the same as the stock 4 barrel 351 Cleveland. Same Cast iron intake as the 4 barrel Clevelandīy 1972 the Boss motors were gone. ![]() Spread bore Autolite carb with smaller primaries and larger secondaries Hydraulic cam slightly hotter than the stock 4 barrel motor with a little longer durationĭifferent heads - large ports & valves of the 4 barrel with the open design of the 2 barrel versionĩ.0:1 compression (Compared to the 10.7:1 in the 4 barrel motor) It featured: First offered in 1970, the 351 Cleveland motor came as a 2V and a 4V engine. The mid '71 Boss 351 (Cobra Jet) engine wasn't much of step up from the stock 4 barrel motor. New air quality standards put better smog controls on the motors, affecting the performance. High octane gasoline was getting harder to find. Insurance rates were going up on cars with these motors. It was during these years that the performance engines were under a lot of pressure. In mid May of 1971 Ford introduced a new version of the 351 Cleveland motor. The 1971 Boss 351 could be called Ford's greatest performance small block motor. The Boss motor option was called the Boss 351. The heads on the 351 4 barrel engine were very similar to the Boss 302 heads.In 1971, Ford offered only a two barrel version of the 302 motor. Even though the Cleveland 351 came from the small block family, few parts will interchange. The Cleveland 351 is between a small block and a big block. The Windsor motor is considered a small block. Ford offered two versions of the 351 engine, a Windsor 351 and a Cleveland 351.
