My 5.3 swap thread!

Just went through this entire thread, did you ever find a solution to the VDO sensor for the water temp?

I can't remember, but you used the stock 90 burb oil pressure sensor drilled and tapped into the oil cooler block off plate above the oil filter right?

What did you end up doing about the volt gauge?
 
The temp sender, no. I'm going to get a stock sending unit and have it turned into the 12x1.5 thread. That's what most folks are doing. The oil pressure I just got an autometer adapter for the stock 90 oil pressure sending unit for where it goes on Tue ls motor since the computer doesn't need to see oil pressure. I think the adapter I got is on Tue first or second page of this thread. The voltage gauge just worked. I dunno why.
 
I don't see the oil pressure adapter. :dunno:

I see talks about the block off plate but cant pin point the adapter.
 
Kinda, I was wrong and thought mine was 1/8npt like the adapter gives you but mine is actually 1/4 npt. So i also ended up getting a 1/8th to 1/4 adapter...
 
Not worth it bra. There is a dude on ls1tech if i remember right that is taking stock senders and threading them to 12x1.5. my plan, and i my suggestion to you, is to do what another dude did (i'll see if i can find it right after i type this) that just chucked a stock sender up in is drill by the nub and ran the drill and filed down the threaded area until it was the right size to run a 12x1.5 die over it. Feel me? The stock senders have no problem being turned into 12x1.5 from the original 3/8 npt.
 
Also of coarse you can just drill and tap the head to 3/8npt and just screw the stock sender right in. Lots of folks do that too.
 
Little bit about it here with the dude that does them for people,

Info on drilling the head hole,

Stock vs. re threaded,

O wow that is awesome I will definitely read up on this., I just don't trust myself to do this and would rather pay someone to do it.
 
Any idea what the guy on ls1tech is charging to turn that sender down to fit? I checked that link but it left off at the point where someone asked him.

And to clarify...what is it about the stock LS sender that keeps us from using that one?

You and me both. But im willing to try the drill chuck/file/thread with a die method.

I THINK he is charging $30 plus the price of the unit. The "stock LS sender" is the one that sends info to the computer. They dont have a separate one for the gauge. From the computer it gets spit back out to the gauge. What that signal is like, i will never know! BUT, There is word that a stock sending unit for like a 97 camaro is a three wire unit where as the normal LS units are two wire. This unit screws right in place of the stock LS two wire for the computer. The third wire on the 97 camaro unit will elegedly work for the stock older style guages. That will require more research on your end. I decided it wasnt worth messing with.
 
Gotcha. Sounds easy enough! I wonder what my machinist would charge me to turn down one of the stock SBC senders. Hmmmm...

I will give this a try and report back.
 
Man i tell ya... Anytime i have a slow day at work and i reach the end of ck5, i travel over to some LS sites. Like LS1tech and performancetrucks etc. They are just as bad as here with giving me bad/expensive ideas!!! All i wanna do now is build bad ass LS motors and stick them in everything! Want a 400hp DD motor that idles like stock and gets 20mpg? LS can do it! Want a 650hp turbo motor and dont want to break the bank? LS can do that too! Bagh! Being a gearhead without a ton of money and time is a challenge!
 
Havent done much to the burb lately but i did clean the engine compartment up from the dust that had been collecting. So, out of boredom, here are some pics from today.





 
I have one but it doesn't match my intake. Its a different year. But I do intend to put it on! Thanks for the reminder actually. Might work on that today!
