98 Silverado LM7/SAS project

[iridektm]

Got a little bit done over the past few days, not much to show pictures of though.

I have the engine/transmission in its final resting place, got the Trans xmember modified, made an EGR block off plate, spark plugs and wire in, fuel lines run and a few other odds and ends.




EGR blockoff


Not much left to do. Waiting on my harness before I put the front core back together.

Few questions:

Whats the best way to use either the OBS or NBS coolant reservoir? The NBS has a much larger hose fitting at the bottom of the reservoir compared to the OBS. Not sure what to do on the plumbing for this part.

I am relocating the battery to the drivers side, does anyone have any pictures of how they mounted it? Going to do a search in a minute.

I also am ditching the ABS. I need the line nut sizes for the front brakes that go into the ABS brain. Cant seem to locate that information anywhere.

(its the 3 small lines)

Thanks for the help

Got a good bit done yesterday.

Biggest accomplishment was relocating the battery tray.

Cut the tabs off the old bracket

Mock up for the leg


Finished


I've got everything ready to go just waiting on the harness. Still not sure how to plumb part of the cooling system and which reservoir has been working best.

What are the wires that come out of the passenger side firewall on the LT1 harness?

Going to the junk yard today in search of a driveshaft

Wanna make me one and mail it over?

Ive been meaning to make one myself for the last 2 years it seems and just never get around to it.

For the brake line ends, i had to reuse mine. Think they are metric though.

FWIW, I used a Moroso expansion tank on my last project OBS truck I did.

FWIW, a new factory left hand mount battery bracket is cheap from GM. I did one on this project, too.

I am trying to find the line nut size so I can buy a Tee fitting to fit the line nuts when I ditch the ABS unit. I plan to reuse the stock line nuts just cant find there size anywhere. Did you keep your abs?

I found a couple expansion tanks at the junk yard today. K10 tanks should fit and I found a few Silverado tanks that might work. Also found a few trucks that have the same front frame horn as me with zero damage. I am wondering if I could cut the junkyard frame horn off and somehow fit that back on...

I found a battery tray on eBay for cheap but had a day of leisure working on the truck so figured I would mess around with the tray.

Jon at Nelson Performance called today. The harness should be back to me on Friday. Cant wait to get it in.

I will be home from school for the break so there will be some downtime. The goal is to have the swap finished and driving before next semester starts.

I ditched it entirely, was on a 99. Just got a prop valve off of ebay since the factory prop valve was in the ABS module.

Do you happen to have the part number for the prop valve? Its a 2 in 3 out?

Thanks
