opened up 6.0 and installed all new gaskets and LS2 cam, valves, springs, cam gear,
had to change output shaft on my 4L60E and install a spacer so my 205 T-case can mount on total came out to about $240, i was surfing web all over trying to avoid advanced adapters $800 kit, and was told cant be done, well they were wrong :laugh:,

only mods needed to do to truck so engine can sit was cut a notch in the cross member so oil pan won't hit, and cut a small notch on frame so my header would fit

also had a ssbc big caliper and disc kit that i just installed and finally new hubs

ADVANCED ADAPTERS ALSO HAS A SMALLER KIT THAT WORKS PRETTY GOOD,contains shaft and spacer i beleve kit p# is 50-6902 but its still about $500 so i did alot of searching, but it paid off:D

hey sreidxmx, your out there by white water right?? sux they closed that place down i use to go every weekend since i was in my moms stomach haha
learned how to ride, fall, and drive there lol
 
I am and yea it sucks cause that place it 10 miles from my house.. I have never actually wheeled there but might outlaw it when the blazer is done.. Then I could actually go "fast"
 
haha, i no we use to when they first closed it down, 4 of my cousins actually got tickets for trespassing lol
 
damm haven't worked on my truck or updated anything, been so busy at work finally putting time aside for this sunday, hopefully finish last touches and start it up, just came up on some ground hawgs on Wednesday also
 
finally did some work this past weekend, radiator, hoses, starter tranny lines, connected ECM, and herd my baby burr on sunday all i have left is to connect the throttle and run ignition switch and she is ready to drive on the road
 
damm haven't been on here in a while, been doing a lot of work to my k5 though, installed all the wiring, ecm everything is dialed inn, fires right up, but then :angry1: problem with my throttle pedal, wasn't receiving signal to throttle body, took a few days but found a short in the wiring and the harness i had was incorrect, for the pedal, now she fires up idles smooth, & real good throttle response, last piece to the puzzle... speed sensor got to fab a way to mount it somewhere, decided on machining output shaft of t-case to press on the reluctor wheel, and mount bracket for speed sensor, itas been a long project but finally almost back on the road, i went to dmv Thursday paid for tags to get her ready haha, so excited:grin:, also scored on a brand new soft topper top for $250 brand new still sealed
