Update..

Chainsing an oil pressure issue. I can't get oil pressure. I have a new pump and o-ring waiting at the dealer for me. Hopefully it's that simple.

 

make sure that it's the red one, here's the differences - credit goes to Quik for the pics.

 

Yeah I ordered both red and blue o-ring along with a new LS6 pump. I used the red o-ring and packed the pump full of pertroleum jelly. Pulled the plugs and injector harness. Turned it over for about 10 seconds, with in 3 I was at 20psi and by 10 I was at 30psi. Let is sit a minute, did it again and instantly had oil pressure (20psi, by 5 seconds I was at 30psi). Tomorrow I'll hang the pulley and misc stuff back on and fire it up.

Little 223/228 sounds mean

 

Sounds good.

 

god damn thats a nice truck man

 

my harness was cut right behind the intake. I am trying to splice it together. what wires do I need to keep? all of them?? I dont want to splice it back together just to remove a bucnh of them later?
any help would be great, I will update my project 50 LQ9 thread, I am on all four wheels!

 

just saw this thread for the first time! i have a 62 c10 that i have been wanting to swap a genIII into! great project man! i envy you!

 

I assume your talking about the LSX harness being cut. Do yourself a favor and order a new one from GM. It was much nicer as the wires haven't been heated and formed to a specific shape. Also you don't have to do a ton of tracing to figure out what is what.

 

Did you have any major problems mounting the LS engine in the frame or your 63???
