Re: 1969 Short Wide

Great idea on offsetting the motor mount stand to clear the A/C compressor.

Thanks, I hope it all works out when I get the cab mounted. It should, if I planned right. We'll see.

You're welcome! I'm glad if I give someone ideas outside the box. Easy-outs are prone making the problem worse. I have literally pulled hundreds.....maybe thousands of broken bolts, screws and taps over the years using this method.

Thanks! Not at all. Simple, clean and removeable if I decide to move the stand. 1/4X2" angle iron. I can give a sketch if you need it too.

Thanks, I'm thinking I'm about to get to the easier stuff after I finish the exhaust and running gears. Body and paint work I can handle. All this motor conversion is taking a ton of time. Pretty sure it will be well worth it

Re: 1969 Short Wide

It may not look like it but, I have been hammering hard on this the last two weeks. I am very close to having the stand alone wiring done. It takes a non electical guy like me many many hours to modify one of these harnesses. I have had a ton of questions to board members Ben (usmcchevy) and Rex (RocketKing) THANKS guys! I'm sure I will have a bunch more questions by the time I get it on the road.

I sent my pcm off to Brendan at Lt1swap.com. Just need to do a few hundred little things and I can test fire the engine

Got the LS1 manifolds cleaned up and welded all the emission bungs up on them.











On to the wiring:






Stand alone fuse/relay :

ran out of fuses but you get the idea:

Re: 1969 Short Wide

Holy cow! Talk about spaghetti junction. I would pull the rest of my hair out if I had to deal with those wires. Hell I would probably roll it at to the street and put a sign on it FREE take it home with you. LOL Good Luck

Thanks and I don't have to worry about hair it's just about all gone already
I thought the same thing when I first started working on it. It's actually pretty straight forward. The hardest part is coming up with the road map of what to keep and what to trash. There is tons of info on the net and good folks here that help too.

I'm hoping to mount it right behind the A/C controls. Not 100% sure since I don't have the cab mounted yet. I'm not sure I have enough length on the wires? If I can't there will be a clever box built to house it and the fuse/relay center under the hood.

Looking forward to getting the exhaust, driveshaft and anything else on the drivetrain done so I can get to the cab and body.

Re: 1969 Short Wide

Nice progress. I made my own stand alone harness on an LT1 swap I did to my old 67 Chevelle. That was an experience and a half but it worked in the end and saved me a pretty good amount of money. I think it was worth the effort and I understood the systems better afterward too.

Re: 1969 Short Wide

is that a Painless Circuit Boss Mike? If so....be careful with that rubber top/seal. Nothing but resistance/friction to hold them in place and somehow mine fell off during a test run. Luckily they sell replacements, I think at $7 ea.
Otherwise I think they are a great alternative to a new complete harness....have all my new power circuits on one too!

Thanks, It is definetly a huge learning experience. Wiring is my single weakest point when doing a restoration.

Kurt,
Actually, I used the list of parts and suppliers HERE. I added 4 more circuits recommended by USMCchevy.

Sure, No problem. I used THIS from lt1swap.com and combined the diagram from Ben HERE

The lt1swap.com uses 3 fuses for all the circuits. I think Ben (usmcchevy) design his diagram after the oem fuse setup. All I did was copy what these guys did.

Sweet. Good plan- fused like stock. That's one of the downsides to the lt1 swap guide. This way is much better for troubleshooting should the need arise...

Re: 1969 Short Wide

Small update. I made a few parts to help mount my fuel supply line. I'm hoping there won't be any issues with this route I took. If there is well.....just have to change it I guess

Then I cut up the two piece driveshaft so I could get a one piece made. Got it made last week, it fits perfect. (thanks Scott62!)

Spacer and angle mount for the fuel line:





Cut up my two piece driveshaft:


Using it to measure the new length:
