Default 1994 ECSB 5.3/4L60E swap

well it's been a long time since i've posted on here...i lurk on the site and never really reply.
well this all started out when the tranny went out. its a 4L60E. so ive started to do a LSx swap. ive pulled the shrouds and radiator, alt, hoses, battery. nothing too special its just a beater with a perfect AC 4 brand new general grabber AT2 tires which are F'n expensive wth was i thinking???! im not going crazy with the truck, i just want to jump in it and beat on it all day and if i had to drive it to new york i could. take it to the track lay down a high 14 and still be dependable.
list is short but its all ive got so far.

tune is already worked out(100.00)
upper and lower radiator hoses(45.00)

i picked this combo up
2008 5.3 Vin# J 1,000 miles 2006 4L60E 22,000 miles.
now all i need is my adapter plates, wiring harness, fuel line, fuel pump, radiator, e fans, tune.

before i tore anything out of it lmao





been on nights this week, so i havent gotten much done other than mounting my external tranny cooler.

there's one more bracket that goes at the bottom but i think this is gonna be ok so i'll see how it goes.
i want to put compression fittings on the cooler into a SS braided line and go to a -6AN fitting into the radiator cooler that way it looks cleaner than the crap that comes with the cooler itself. the cooler isnt very big but then again im not running a huge cam or a large stall (TB Stall) so i think it'll do. only had to drill 1 hole on the left of it to mount to the AC Condensor and a hole in the bracket to mount to the cooler itself. so it was really simple.

i should be picking up my motor and tranny tomorrow but it'll be on a pallet for a week bc ill be on days this week coming. but while i wait on my stall and adapter plates to arrive ill go ahead an do the servos and shift kit. i want it to shift firm at part throttle and firm on the WOT. i just dont want it to snap my neck everytime it shifts at part throttle.

small update
enjoy.



2008 5.3 1,000 miles




i don't know why it looks like the top of the valve cover has runs in it. it's in the cast i'd guess. oh well, you can't see it anyways.

Chevy Orange 2000*F

well works been hell so i havent worked on the truck any. i ordered a powersteering pump an bracket, a 99-02 valley cover with knock sensor harness. i ordered the LS7 7,000rpm lifters and LS7 lifter trays. i had to order new head bolts, and head gaskets. i picked up a new toy for the truck but its a secert
im also going to mill the 799 heads .030* to make them true, also going to be running a
220/224 .581.588 on a 113+4 LSA with 4:10s

it should be a low 15, high 14 truck and still get 17-18mpg

im not painting the truck or anything fancy other than a newer grille and front bumper may do head lights and turn signals too, dunno yet

now im in the market for an LS2 valley cover because i cant use my DOD cover anymore. i finally brought my motor home and got it on the engine stand covered up good. ive got a huge pyle of parts in my closet, shed, bedroom lol. its at the point where my fiance' is tired of seeing Summit boxes and all the UPS boxes lmao. oh well.
i have some pictures of the motor being torn down to the heads, non of the motor wrapped up i didnt think about it.

BTW this is a GEN IV engine and theirs no knock sensor bosses under the valley cover so i am having Jon at Nelson Performance wiring my knock sensors for outside of the motor vs their 99-02 connector. also the injectors on my motor arent the same plug ins as the older motors.

i think the cat is out the bag about my secert.
90mm Plate system with either a 125-150 shot. 10lbs bottle.

Cool build - that poor little V-6 must've been DYING when trying to move the truck with any kind of load on it... Don't know what bonehead at GM dreamed that combo up...

I'm going to be paying attention to this one, since I'm giving serious thought to dropping a 6L into my camper/tow-rig (similar year). (Gonna need more than the stock TBI 350 to haul the camper on the back while towing my GTA over the Rockies to Bonneville!)
