What kind of electronics are you using for the conversion?Original owner of a 2002 Suburban Z71. 280K miles on original engine & transmission. Still runs good but engine has made a lot of valve train noise for the last 200K miles & I don't trust it. So I'm about to replace engine & trans with 6.2 LS & 4L70E. After that I plan on putting some overland gear on it and drive around the country for a few months.
