Leave it to to build an all-out performance to replace the LT1 Optispark! We machine an entire billet block of aluminum down into a housing that fits in place of the piece. Then, we fill it with a new pick-up assembly, a trick timing adjustment mechanism and top it with an all new cap! The pick-up is an advanced optical encoder, a different style of optical pickup than the . This type of pick-up has to be very 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 that offers timing adjustability! An adjustment screw allows the timing to be tweaked up to /-5°. The is equipped with a fresh and has an extra thick mounting surface for the cap to leaks. The is supplied complete with our LT1 Cap, Rotor and the required for installation.
Advanced optical encoder trigger design for accuracy and reliability.
Easily adjust the timing up to /-5°.
Improved housing design and extra leaks.
Fresh vented and to keep the out.
Large ball bearing stabilizes timing through 10,000 rpm.
Rotor drive design is positively indexed and cannot slip.
For 92-94 LT1 engines, supplied with fresh hoses.
Incorporates our own trigger wheel and encoder. This trigger process is much more and through high rpm.
