Leave it to MSD to build an all-out
performance distributor to replace the OEM GM LT1 Optispark! We machine an
entire billet block of aluminum down into a precise housing that fits in place
of the factory piece. Then, we fill it with a reliable new pick-up assembly, a
trick timing adjustment mechanism and top it off with an all new MSD
distributor cap! The pick-up is an advanced optical encoder, a different style
of optical pickup than the OEM. This type of pick-up has proven to be very
reliable and stable through extreme rpm and conditions. The rotor is bolted to
a drive assembly that is indexed to the shaft and is stabilized through the
use of a large ball bearing assembly. Once installed, you have the ability to
adjust the ignition timing – the only distributor that offers timing
adjustability! An adjustment screw allows the timing to be tweaked up to
+/-5°. The distributor is equipped with a fresh air vent and has an extra
thick mounting surface for the cap to eliminate leaks. The distributor is
supplied complete with our heavy duty LT1 Cap, Rotor and the components
required for installation.
For '92-'94 LT1 engines, supplied with fresh air hoses.
Incorporates our own trigger wheel and digital encoder. This trigger
process is much more reliable and accurate through high rpm.
