Re: LS swap for my 75

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

Re: LS swap for my 75

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

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

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.

Re: LS swap for my 75

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

Re: LS swap for my 75

$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.

Re: LS swap for my 75

He's local. I got it all button up and the angles were off. So I put a inch spacer on the t case. Hopefully I won't have any vibrations

Re: LS swap for my 75

Ahhhh.....the joys of driveline vibration! Hopefully that will fix it. Be sure to use good quality bolts rather than just using the factory ones. Better strength.

Re: LS swap for my 75

For non-CV drivelines (what you have I believe), you want the t-case angle, and the axle pinion angle, parallel to one another.

In other words, if the t-case is down 4 degrees from horizontal, you want your axle pinion pointing up 4 degrees from horizontal.

Re: LS swap for my 75

Yeah so I used a app on my phone to measure the angles and it was way off lol turned out I was only 3 degrees difference minus the spacers. 7 up front 19 in the middle and 10 in the rear. Spent all day lowering it, moving the shifter linkage, then some how the rod on my column for the key came out so I gotta fix that now. I really miss driving her

Re: LS swap for my 75

I'll check mine in the morning and see how it compares but that does look a little close. How long are the mufflers and how close is the end of the muffler to the rear axle? If they're long mufflers he may not have had much choice.
