I wanted to stop by with my new findings with the 02 hybrid conversion. This winter I did the original lly conversion, with a lot of help from this thread. The truck ran "ok" had lots of rattle and was a bear to drive, but made 511hp on dyno and ran out ok... Well after my wife wrecked her 2.5 truck. I decided I'd start playing with this 02 dually. So Monday I got a wild hair and pulled cab and swapped in a set of lbz heads I had on shelf, Tuesday put in some 60% over LMM 6 holes, and a dual fueler kit. Initial start up I noticed an immediate difference in engine noise and how it ran. It sounded and idled like stock lb7!.... Took it to dan clarkes place and we dyno tuned it. He was able to actually able to trash my tune that I worked on for a solid week to make the old setup to work. Copied over stock lly tables and started dyno tuning. Each tune would gain us 30 more hp it seemed. Ended up with 630/1100 the stock ihi was out of breath. Sorry for the rambling. Got an 8hr drive ahead of me. But my point is. Lb7 ficm/ECM will drive LMM injectors like there's nothing funky going on! I officially have parts from 01-15 engine models all stuffed into one engine. Lol
