Default s475 ly6 swap 4.3 in progress 09' rcsb video

OK finally got the truck ive been wanting for awhile now nnbs !!!!
Did some searching on craigslist for at least a month waiting for good deal to pop up . Sold my 72 nova which had aluminum turbo 5.3 tubbed caged blah blah blah , it was fun but ive been wanting a newer truck .
Scored one on craigslist ,drove 4 half hours to pick it up .Drove the truck back to my house . Pulled the motor/trans setup out 3 days later .
I already have a rebuilt ly6 with head studs, big cam, intake etc , bought a 4l80e off my father . which came out of a box truck , had the parking brake on it .
As of right now most of the parts are ordered to do the swap and a local guy here has a wreck 08' model which had 4.8 . Bought harness off him and few other parts going to , ac lines, radiator hoses, motor mounts .
Truck was lowered already when bought , but i plan on lowering it more, just has axle flipped above leafs , and 2" drop spindles . I plan on notching frame , lowering springs front rear , that should have better stance.

Heres quick run down on parts -
stock bottom end ly6 , top ring opened up
80lbs injectors
twin walbro 450's
stock lines with an adapters -pics later
stock 10 bolt for now with what ever stock gears in it. - ford 9" in future
4l80e with correction kit and single disc converter
s475 t4 divided 1.10 83mm should spool wicked fast with the converter i picked out .
2" cross overs hot side 4" down pipe

ill update with new pics when stuff gets here .

Picture of the nova i sold . I bought as a roller installed motor/trans/ turbo setup fuel etc . Sad to see her leave . This boosted silverado should cheer me back up ha and more comfort to drive .
Waiting on parts to arrive to get this thing up and going

Got the fuel system bout done, the 4.3 has two rails going to the engine bay , ones a feed line ther other i think is for evap , suck the engine fumes out ...?..? idk , but im using the feed line for the feed line and the other line for the return , . it goes to the charcoal canister , im just going to cut it from the canister and run it to the tank , drill and insert a barb fitting top of gas tank for the return . do sway with the evap stuff.
using twin walbro 450s , bought them both with the install kit , filter sock and 6" hose line . put in a y fitting , . wiring it was super easy . came with wiring plug ins , cut them off and used the terminals from the kit for the stock plug in .
