The G-Body Swap Thread
The stock location adapter plates only sits the LSx in the original sbc's location, and with the vehicles stock tranny location theres going to be a gap. In order for you to retain the transmissions stock location you have to get the 1" setback plates, this has been discussed several times in the past. And you also need to understand that the stock tranny location is only useful if you're running the vehicles original trans, anything else is subject to fab and modifications.

Power steering pulley clearing on Gbody I used to stock truck power steering pump and pulley. Works just fine on my swap. The only catch is if you go to replace the power steering pump the pulley will just touch the box as you have almost pulled it off the shaft. And when you go to put the pulley back on the new pump it will start to pull on at a slight angle and then straighten out as you pull it on further.

pwr pulley I have a 5.3 with the truck accessories. First off I'd like to say that the Ford Econoline power steering pulley clears the MCSS steering box in my car with motor mount adapter plates that do not set the engine back. The factory belt seems to be tight enough too so no need to get a slightly shorter belt.
My question is about the power steering lines. Should I use factory MCSS pressure and return, factory truck lines, or some combo of both? I know some people are running truck accessories so this has to be an easy question to answer.
TIA

I used custom mounts that replace the frame side, they were made by a member on the forum for his personal swap and I picked them up off him when he parted his cutlass out. They would probably position it close to the 1" back mounts.
Ok I have tried to do alot of reading on this and I am just going to ask it anyways. Me and my brother are starting to dump some money into the 85 MCSS and he wants, as do I, to do a lsx swap into the car. Well we both do not have alot of money to put into it. He'd rather do the lsx for the modern technology, better mpg capabilities and for the same reason I want to...for the wow factor. Well in saying that, if swapping a bone stock motor in there lets say a 5.3 or a 6.0 from a chevy van/silverado...can it be done relatively cheap?
I am not sure b/c I have read alot on headers but would the stock manifolds work or do you have to go with headers? Again Id love to do the lsx in it but being that it already has half the things inplace to do a old sbc 350 in there, that would be tempting to keep the cost down. We both arent mechanically inclined enough to do this on our own, so the help of others would be needed.
Down the road I want to convert it to the car intake and do the whole FRC and such to make it look good but to get the motor in there and running I can deal with the ugly truck intake for now. But with that, would the wiring harness need to be modified to mount the car style intake on it? would it be best to just wait for a car intake before doing it?
Im just stoked to start working on the car I just want to get better idea and all on guys whos done this before. ANd I know from past experience with the s10 that its easier to do engine upgrades with it out of the car but a stock 6.0 has enough power to hold us over for one year i would say, lol

depends on what you consider to be cheap. Vette or fbody factory exh manifolds will fit, the truck harness will work on either intake but you will need injector harness adapter when you decide to switch to the car intake. Truck intake will clear the hood if you get the correct frame and block mounts(short/wide). Look at the budget friendly sticky on page 1 and it will give you an idea of how to pull it off conservatively.

Alright fellas, i got the lm7 in. power steering clears, transmission mounts right up. everything is good, except i cant get an exhaust job on it. although it sounds pretty cool with open exhaust manifolds, what kind of headers should i go with. ls1 longtubes??
I just found and got a response for a lm7 5.3 full motor including wiring harness. Motor just needs a water pump but it dies have high miles 200k. Now here's why I smyrna interested in it...its in the truck still and they are chopping it up using parts off it from what they need. They told me 200 for the motor and wiring but than said they might just give it away to me with the cab forward BC they just want it gone. So I found get it for free than take the truck to the scrap yard and make hopefully most of the money it would have cost to buy the motor. Sou d like a decent deal?
Here's a g-body getting the LSx treatment with plenty of good pics and info regarding mounts, oil pan, and headers. https://ls1tech.com/forums/conversio...u-ls-swap.html
