LS swap for my 75

[lowrodderchev]

Things are going little slow. Mainly missing parts and a few other things. Broke a intake bolt, power steering pump gave me trouble. But other than that she's in the truck. Figured since I pulled the motor I would replace my rusted out fenders to

[lowrodderchev]

Even if I didn't get my truck done in a week glad I got to hang out with my best friend ��

Sweet!

[lowrodderchev]

So I got ahold of this 3/4 ton driveline to replace my 203 driveline. If I shorten will I be good? Or is it to beefy? Lol

[lowrodderchev]

Buddy of mine bead plastic my exhaust and cleared my heat shields

Nice job on Exhaust!

You'll have to really inspect the u-joints or you may want to just change them out as a precaution. Talk to the driveline shop and see how much they would charge to swap them out or you do it, and then bring to shop for shortening/balancing.

Spicer joints

[lowrodderchev]

oh yeah that's the plan new u joints either way. figure everything else is new. First C10 shot me some info on were do get the spline yoke gasket. tomorrow evening I'm going to work on new u joints on both front and back drivelines

[lowrodderchev]

I just thought about it last night but can I even shorten this driveline? I need to cut off a few feet. I wasn't sure if its possible because its tapered

[lowrodderchev]

also took a cruise this morning to pick up my wiring looks good cant wait to put it on. to bad I gotta work today

[oltronj]

Looks like a good project. Been thinking about doing an LS swap on my 90 Suburban. Lots of good info here.

[lowrodderchev]

When it rains it pours . My slip yoke has a crack in it lol FML

[68Timber]

Ouch. Good that you caught it tho.

[lowrodderchev]

Yeah my buddy sand blasted for me and he notice it. Anyone know if I could use this for my rear? It came off the front just want to use the double shaft at the yoke like they did on the pic

[lowrodderchev]

what a week. so still buttoning up things but seems like it isn't going to good. I'm wishing I would have stuck with a 350. took my front driveline in today to get new u joints. I would normally do it but I don't have the tools to melt out the plastic clips that hold it in. anyways $150to install 2 splicer u joints OUCH. I still gotta take him my rear shaft to shorten ($95) plus new u joints for that. took my radiator in today just to check it guy suggested I just get a new one since that one is original. he quoted me $350 for a new one. any suggestion on were to buy a nice one? thanx

[68Timber]

$350 might be a fair price if it's his premium radiator. That's in line with prices I've checked for mine at rock auto for their best. The Champion aluminum radiators are much cheaper but it seems like everyone has to massage the mounts to make them fit. Maybe I let that mess with my ocd more than I should though. Keep after it, you're almost there.

That's the rear shaft in my 87 Burb, had it built. You probably already know this but if you use a double cardan it is recommended that you have no angle (Zero Degrees) at the axle pinion.

No I didn't but its good to know. I'm taking my rear driveline in tomorrow see how it hoes crossing my fingers

[lowrodderchev]

What's a thread without pix. Painted my front radiator support pieces

[lowrodderchev]

Few undercarriage shots

[lowrodderchev]

Fuel lines and new tank(yeah I still need to bolt down the fuel lines)

[lowrodderchev]

The driveline is just a mockup to see how the angle was

[lowrodderchev]

I'm thinking of starting a website for ls swaps negative side of the coin lol I ordered the wrong radiator its the one called for my truck but its to tall

[lowrodderchev]

Finally got my drivelines back buuuut lol guy put larger u joints for a newer truck not a 75 blazer with 1310 u joints so tomorrow I gotta shoot the drivelines back to him and well see how long it takes

[68Timber]

I don't speak LS very well either, I'd be making those mistakes too. What radiator did you end up going with?

[lowrodderchev]

I got a champion radiator pretty nice though just wrong one. There going to swap me out for another one but just one more thing I gotta wait for
