wow Mike!!! already learned sooo much from your thread!! thanks for the pics and details....currently getting ready to start tear down on my 67. Have a vortec 454 and 4l80e out of a 98 1 ton with all the harness and ecu for both the motor and trans, and was recently wondering what to do about the fuel system.....your last few post answered that for me now just have to figure out this harness and computer.....lol

[mcbassin]

I installed the starter tonight then started trying to figure out my exhaust manifolds. It looks like I may try to go with LS1 manifolds from a Camaro. My buddy gave me his from his project S10 he replace with headers. They fit without any cutting into the frame. Not sure if I can find the flange adapters in a salvage or not?

Then I ran into a snag that took a bunch of time. The P.O. broke one of the driver side bolts off. It was an easy fix so I thought I would document it and share it here.

Also, for you LS guys here is how braced the passenger side engine stand to accomodate the stock A/C compressor.




LS1 Manifold:


Broken manifold bolt:

Clean the stud good, then get out the tig welder, then build up the stud until its about 1/8" past the surface. I like to use high alloy or stainless filler rod.
Since the head is aluminum there isn't as much chance of distorting the area around it. this technique works with iron heads too. Just be careful.



Then I weld a 5/16" flat washer to the petruding stud. I weld it very solid and get it good and hot (glowing red) This heats up the loctite and any debris that caused it to break in the first place.


Channelock pliers work great


Done deal, I'll chase the threads with a tap before final install.

Thanks for the kind words.
That's an awesome motor/tranny combo you have.

I know some guys on here that will glady help you through the TBI install like they did me. HEREis a good thread to get you through the install.

For your fuel pump you will want a low pressure model. I recommend THIS one.

Looks good mike!! That's a good idea on the broken bolt..

thats one hell of a tutorial thanks for the link. Mine is a MPFI system, so will need to look for a different wiring diagram, but that definitely makes it look more manageable than I thought....and with MPFI, still a low pressure fuel pump?

Thanks Kyle, it works ten times better than an easy out. Trust me.

Oh, My mistake. I thought that the TBI was used all that way up to LS. That shows what I know. Not sure about the pump? You can ask some these same questions on the engine and drivetrain section. There will be some guys that know about it on there.

Your power train is looking great! Great write up on the broken bolt removal. You can also use a nut one size or a couple sizes bigger than the broken bolt that way you can use a wrench or socket to remove them too.

Looks awesome as usuall! I really like the bracket for the passengers side motor mount.

Hey Ryan, Thanks for good words. Yeah, I have used nuts before too but you have to build up the stud a lot more and it can be a little trick on a verticle job like this one. But on bigger studs that take a lot of force that's the only way to fly.

Thanks Ben! I really didn't want to weld something in permenent. Heck by the time I get this on the road LS will be obsolete so I may need to do a whole different set up.

That was a great idea on removing that broken stud....thanks for sharing

[lolife99]

Like always,... nice work!

[chevy71c10]

Great progress! nice job on the broken bolt. Keep the pics coming.

[RocketKing]

Excellent job!

[68 TT]

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

Thanks, I hope someone can use it.

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

Thanks Mike, for the idea on getting the broken stud removed. Perfect timing too. I have 2 of these engines sitting in the garage, and wouldn't you know that both have a broken manifold stud on the driver side rear. Thanks again. Your progress is looking great!

Genius! Mind if i steal hat?

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

[mcbassin]

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:

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.

Where do you plan to mount the ECM? Looking good

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.

[68 TT]

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.
