    You could also use a Vortec 454 front timing cover(to hold teh crank sensor) and the GM L21 454 24x reluctor. The L21 454 was a BBC that used a 512kb dual 80 pin PCM(like the 0411). It came on the 1999+ Kodiac and Workhorse trucks. It was the 1st BBC that GM used CNP ignition and ETC. The internal 24x relucctor costs $18 from GM.

    You can still use the Vortec distributer for a cam signal, and you can run Coil Near Plug(CNP). Use a Vette LS1 calibration for ETC, or an LS1 Camaro calibration for cable throttle. Just spit balling here.

    Nice setup you have there.
