The GM LS Series engines are being built for a lot of different performance and racing applications. You can see good ol' hot rodder ingenuity taking place as racers are running carburetors and even using distributors on these engines! These MSD LSx trigger converters plug into the factory crank sensor of an LS engine. They then convert the factory trigger signal into a 12 V square wave signal to trigger an MSD ignition control such as a 6 or 7 Series ignition control. If you are incorporating a front mount distributor into your LS engine, this means that you won't need to run an external crank trigger.

Go Fast Bits Mach 2 upgrade kits convert blow-off valves from recirculating to atmosphere venting. To vent the Mach 2 to atmosphere, you need to ensure the piston stays closed at idle and the recirc hose is plugged. The 5930 Atmosphere Conversion Kit includes a 30mm hose plug to block off the recirc hose, a trumpet to replace the hose outlet on the Mach 2 (not necessary for functionality, but makes the sound louder!), and a firmer spring. The Mach 2 is supplied with a softer spring that's suitable for recirculation venting or cars with idle vacuum of 18inHg or less. If the piston stays closed with the existing spring in the Mach 2, there is no need to swap it out. However, if the piston hovers open at idle even with the spring pre-load maxed, the firmer spring in this kit should be installed to prevent stalling or backfiring.
