This cable drive vehicle speed sensor provides a speed signal to your engine computer (4000 pulses per mile). Threads onto speedometer drive cable on side of transmission or transfer case. Includes wiring harness to connect to your engine computer. Call to discuss your specific application.

This conversion harness allows the installation of the larger, 90mm, four-bolt, Electronic Throttle Control LS2/LS7 CAR throttle body on 1997-04 Corvette LS1/LS6 engines and 2004-05 Cadillac CTS-V LS6 engines that use a 76mm, three-bolt ETC throttle body. It is great for use with FAST 90mm inlet manifold or supercharged applications. It also facilitates installation of LS2 and LS7 engines in the above vehicles.

This conversion harness allows the installation of the larger 90mm, four-bolt, Electronic Throttle Control LS2/LS7 CAR, four-bolt throttle body on 2000-02 5.3 and 6.0L engines and 2001-02 L18 8.1L engines that use a 76mm, three-bolt ETC throttle body. It is great for use with 2005-06 SSR and 2007 truck 90mm inlet manifold or supercharged applications. It also facilitates installation of LS2, L67, L92, and LS7 engines in the above vehicles. NOTE: This harness is not intended for use with truck 8-pin 90mm throttle body. It requires a passenger car LS2/LS7 90mm throttle body.

Use this EGR block-off plug when removing the EGR tube from a truck or Camaro/Firebird inlet manifold. Bolts in place of EGR tube and includes gasket. Also great for engine dyno use to install thermocouple fitting and monitor inlet air temp or nitrous oxide nozzle installation.

Installing a Gen 1 or Gen 2 small block or big block transmission behind a Gen 3 or Gen 4 small block (2004R, 700R4, THM 400, THM 350, T-10, 4L80E)? This spacer moves the rear crankshaft flange back to the location found on earlier GM big and small block engines. This spacer can be used with our conversion automatic transmission flexplate/bolt kit or our conversion flywheel/bolt kit. Note: Some 4.8L and 6.0L truck engines were produced with a special long crankshaft. This spacer is not required on those applications.

Installing a Gen 1 or Gen 2 small block or big block transmission (2004R, 700R4, THM 400, THM 350, 4L80E) behind a Gen 3 or Gen 4 small block? Use this flexplate and bolt kit with above crankshaft spacer. This kit contains a flexplate drilled with six torque converter attachment bolt holes 11.5-inches in diameter. The 11.5-inch bolt pattern is used on the 4L80E torque converter. When using smaller diameter torque converters, re-drill three of the holes to the smaller 10.75-inch diameter bolt pattern. Contains six special length crankshaft bolts. Flexplate is neutrally balanced.

This cast aluminum oil pan allows the installation of the Gen 7 big-block L18 engine into past model GM cars such as Chevrolet Impala, Camaro, Chevelle, Nova, Monte Carlo and other GM A-,B-,F-,G-, and X-cars from 1966-96. The CNC-machined groove in the pan rail accepts the new O-ring L18 gasket. The pan also allows use of the L18 dipstick and tube as well as a threaded boss to retain the low-oil level sensor (works great as oil temperature sensor location too). The kit includes a revised oil pump pickup tube and bolt-in oil pan baffle. Note: This product requires removal of L18 windage tray and main cap studs to clear revised pan design.
