Thought I'd post up some pic's of my turbo propane truck project. It's a 97' Chevy 2wd RCSB originally a 4.3l/4l60 truck. Here are the specs:
2003 6.0l LQ4 with unknown miles
Z06 cam and springs
Vic jr intake + 6010 msd box
Dual Impco 425 mixers with dual Spectre Carb hats
Magnum XT80 turbo 1.15 ar exhaust housing 4" down pipe
th400 3600rpm B&M converter
It's pretty close to being running, should be running in the next week or so. Thanks for looking!

Ya the main reason I'm doing propane is because it's cheap, $2.00 a gallon right now and 105+ octane depending on what time of year. Mileage would be comparable to pump gas and the truck has a 35 gallon tank that sits in the box. I'll get some pics of it when I get it mounted. Here are some pics of the factory wiring that I thinned out "alittle"

Got my thermostat issue figured out last night, wanted a straight outlet instead of the angled housing trucks come with. Took a themostat housing from a 04' Savana Van with a 2 piece housing, cut it, rotated it and welded back together, worked perfect and way cheaper than a csr housing.

It has a WOT mixture screw and a idle mixture screw everything between is adjusted with different air valves, but as long as it has enough fuel at WOT under boost, I,m not to worried about the rest.

Thanks, just got it running a day or 2 ago, took it for a rip and it seems to spool pretty fast. it's rich down low and lean up top so I have some work to do. I was going to mess with it more today but we got a foot of snow overnight so I'll have to wait to get it on the dyno. Here are acouple pics of the pretty much finished engine bay.
