what are the prefered plug wires for this engine. any thing to make sure i stay away from.

 

I would stay away from aftermarket wires. The GM Techs around here install a set of GM wires on trucks with a distributer and aftermarket wires whenever there is a driveability problem.

GM used to use Hewlett Packard, I would use OEM, esp. on teh Vortec 305/350 due too their length. The ARE expensive though.

I got MSD wires and blaster coil. I would stay away from aftermarket plugs if your not going FI or using Nos. I went with the OEM plugs the AC Delco professional platnums. My tahoe has been running better then ever with this combination. I also just got the MSD 6a. I notice a gain in fuel economy.
