LSx Swap '69 C10 Build

[RocketChevy56]

Hey there guys/gals!! been a long time since I've frequented these pages, but its also been a while since I've worked on my 69 swb too! Well finally i'm in somewhat of a level ground financially and I feel I owe it to my truck to show her some lovin for her patience with me the last couple years.

So anyway, I've got a built 355ci sbc in the truck and a 700R4. I've driven the truck everywhere and even DD'd it for a while but i lost oil pressure and more or less blew up all the money I had sunk into the motor.....And so it sat..... Until a CL ad caught my eye. 2003 5.3L with 100k, harness, front acc. and ecu for CHEEEEEEAAAAPPP. Like any good gearhead, I bought it with no rhyme or reason other than to get a deal. Then the obvious hit me and so it begins....

The motor is a clean drop out 5.3L out of a flex fuel suburban. 100k on the clock. The owner had an "oiling problem." his dummy light kept coming on while driving, but no ticking or smoke. A shop put a new oil pump on it but nothing changed, and for some reason a new oil pan as well?? I've checked the bearings and all are perfect. The only thing I found a bit funny was a rtv covered o ring on the pickup which I'm assuming was an issue. feel free to chime in and let me know what your thoughts are on that...

I've decided to keep the 700R4 so I bought a Gm spacer and the longer bolts needed to space the trans accordingly. I bought a set of Edelbrock ceramic coated shortys that will suffice until I can work a set of long tubes in there.The mounts are the tubular swap mount perches from CPP with Poly mounts.

I've started digging through the harness and cleaning it up. I can't bring myself to buy the swap harnesses for $500-800 when I am pretty confident I can make the free one work just as well if not better.

Anyways, thats where I'm at and will post pics as soon as I start getting stuff done. Any and all input and Ideas are welcome, Thanks for all the upcoming support and advice!!!
