Description:
Finally, all-out performance distributors to replace the OEM GM LT1 Optisparks--MSD's Pro-Billet LT1 distributors. They feature a precision-machined billet aluminum housing that fits in place of the factory piece, a new pickup assembly, a trick timing adjustment mechanism, and a new MSD distributor cap and rotor. The pickup is an advanced optical encoder that 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. The distributors use an adjustment screw to advance or retard the timing by up to 5 degrees.
