My 6.0 swap into 82 Chevy

Sounds GREAT   What cam do you have in there?

[team39763]

Thanks.  I'm hoping to get another video of it from a better angle so you can actually hear the mufflers.  Here's another video my wife shot a few days ago. The cam is a Comp Cams 226 grind with 580ish lift.



The throttle got stuck while I was trying to start the truck and I waited a few seconds to see if it would come back down, so then I kicked the pedal and it backfired(but it came back to the 650rpm idle).


I messed with it today and I think I had the cable and bracket setup wrong, so I fixed that and the pedal feels a lot better now.  Next I'm gonna see if I can borrow a wideband O2 sensor from somebody or jump on a dyno somewhere and do some tuning.  I guess I should have bought my own wideband O2 before I went and bought that nitrous kit.

man that's music to my ears!  that's sounding GREAT, truck looks nice too!  i want to see a video of this thing once you "let 'er eat!"

[team39763]

This sucks, I can't get it running again.  It'll start and spit and backfire through the carb the whole time.  Sometimes I can get it to idle, but like I said it definately ain't right, spitting and blowing white smoke through the carb and it shakes the whole truck.  It won't rev without backfiring really hard, even at that, it'll only hit 2000rpms and eventually stall.  What could be causing that?  I'm no mechanic, and I don't know what to check.  I tried all 6 different timing pills, I have constant fuel pressure, but my plugs are still fouled.  What do you guys think?

[Fordeatinz71]

honestly, it sounds like the timing is off.  you might have lost a sensor or your MSD box could be on the fritz...

Yep, what he said.

[team39763]

I still can't get it started, and I don't know what else to check.  I already arranged for the truck to be picked up and dropped off at a Dodge dealership in the next town.  Hopefully they can get it running.

Are you getting spark and fuel?

[team39763]

I'm sure I'm getting fuel, spark may not be as strong as it should be, but I think it's there.  I'm pretty sure I need a new set of spark plugs, mine have been fouled 9 times already so I think it's time for a new set.  I also think I had the coils flipped around backwards, but I'm not sure if that made a difference(but I really can't tell which way they go...YOU?).  I have a gut feeling that it's the MSD box, either it's defective or I wired it wrong.  Can any of you guys tell me - is the power wire to the distibutor hot while cranking and in the on position?  That's what I'm using for 12volt power to the msd box.

[Captkaos]

Not sure what you mean about the coils being "backwards" you could mount them to the firewall if you wanted..  The original distributor wire is switch power as you described.

[team39763]

I was told that the right bank and the left bank have their own set of coils - they have two different part#'s.  I'm guessing switching them is like having your distributor 180* off??? Does that make sense?  I'm gonna call up a GM dealership and get the story on that just to know for sure.

[Captkaos]

Coil packs aren't specific to left/right sides if that is what you are asking....

[team39763]

Not the individual coilpacks, but the electrical connector that fires them.  I don't know...I think I confused myself.LOL.  I've been reading up on EVERYTHING I could find on LS1's, trying to figure out what the problem could be.  On my motor, the electrical connector on the passenger bank has an even number and the driver side has an odd number.  I'm just gonna send if off to that Dodge dealership and pray for the best.

[Captkaos]

The connectors are specific left to right.  Does the MSD setup batch fire the coils or sequential fire them.  If it is the former, it doesn't matter.

[Fordeatinz71]

just curious...why are you sending a GM to a Dodge dealership?
