My 6.0 swap into 82 Chevy

[SatisTraction]

you want the fuse to be as close to the power source as possible. Dont give up on the conversion. try this site for more LS1 help.

tons of swap knowledge here

HAHA!!  I got to hear it run today.  I'm excited and a little disappointed.  It didn't sound like I expected it to.  It also had tons of gas leaks, so that's an issue right now(tightening fittings didn't help much, so I must have forgot to put teflon tape/sealant).  I'll see if I can post up a vid soon.

Gas will eat right through pipe tape unless they make a special kind. I tried using pipe tape on a thread once and it pretty much melted it.

[team39763]

Oh OK, I didn't know that.  I'm gonna run out there and yank that crap off there and put some thread sealant.  Thanks for telling me.

What kind of fittings are you using?  AN or compression, etc....

Something doesn't sound right. I don't think you should be using any type of sealer.

[Captkaos]

That was my next response, if it is AN or compression it shouldn't have anything on the threads.  If it is the GM fittings for EFI, they take an o-ring...

[team39763]

I have some AN fittings(which were probably just loose) and I have 3/8NPT fittings where the teflon tape melted as Scottsdale said. A buddy of mine told me to use teflon tape, so that's why I used it.  I went back and put thread sealer on all the threads in the fuel system.  I'm gonna fire it up in a few minutes.

[team39763]

I fixed the leaks.  But it still starts like crap.  It cranks and cranks then it starts.  The idle is ok, but I can't tell much with the open headers(it's just loud).    Could carb tuning affect the start up?

[Captkaos]

Does it do this everytime (the constant cranking).  There is no way I could work on getting one running with open headers...  are you having to give it gas to make it crank or does it fire on its own?

[SatisTraction]

go get some exhaust on it. the open headers will mess up the O2 sensor readings. I jsut completed a TPI swap and it ran like crap until i got the pipes on it.

[team39763]

Giving it gas doesn't really help.  It just starts when it's ready, but it stays running without a problem.  I think I'm gonna take it to a real mechanic to tune it.  I feel like I've done as much as I can do(getting it running).  I'm trying to find someone to do the exhaust the way I want it done.  I hope it sounds good...I got an H-pipe and 10 series flowmasters (3" all the way).

SatisTraction, team39763 is running a carb on the 6.0L so he isn't going to have any ECM issues, and as far as I know he isn't running O2's...

If you know a little about carb tuning you can put a vacuum guage on it and tune it to where it has the most vacuum.  On the adjustment screws I usually start at 2 turns out, and start with 10 degrees initial timing with no more than about 32degrees max.

[team39763]

^Good info.  I'm gonna go look for a vacuum gauge and check and see what the timing is on each one of those timing pills.  Nope, I don't have o2's, but I might pick up a wideband in a few weeks.

I mounted my wheels and tires, now I just need to lower the truck.  I'm thinking about using spindles in the front along with the 2" drop springs it already has.  In the back, I'm just gonna pull the helper leaf.  The truck sits really high in the front for some reason.  For tires, I just have some junkyard tires up front and 28X10.5 MT slicks in the back.
 The pictures really don't do the truck justice.  It looks a lot better in person.
