@NINOBROWN914 An LT1 is a second generation small block, and an LS1 is a third generation, the LS1 engines are completely different than the first and second generation small blocks, but you can bolt up any transmission from a Chevy V8 to any other Chevy V8. You could bolt up any automatic, TH350, TH400, 2004R, 700R4, 4L60, 4L80, or any manual like a Chevy T5 or T56 to any Chevy V8 engine, any small block or big block. They all have the same bolt pattern.
@MrBuick2009 I used the F-body pan, as the engine is out of an 00 T/A. I had to notch the crossmember quite a bit to get it to fit. I wouldn't recommend that unless you have a lot of welding/fabrication experience. I understand that a pan and pick-up from a 4.8/5.3/6.0 will clear the crossmember, but I talked to a guy who was having issues clearing the centerlink. Check eBay, I recall seeing an oil pan and pick-up kit for G-body cars. eBay and Google are your best friends for this swap.
@larry8315 I didn't keep track of exactly what I spent on it. I think I was a bit too scared to do that, but including buying the car, I think I've spent close to $20,000. And unfortunately it's not for sale. Nobody would pay me what it is worth to me.
@bigstuff5 An LT1 wiring is completely different than an LS1 actually. I wouldn't have any idea where to start with it. There's probably a lot of good LT1 swap websites though that should have that info.
hey man i got a 84 monte and rite now it has a 305 n it but i would like swap it out for a 454 bored sumwhere round 90 and just wanted to kno wats the best rear end to put on and will my driv shaft hold up thanks for ur time lookin forward to see ur respondse
@lgibson31 I'd probably go with a Ford 9". Unless you want to keep it all Chevy parts, but the 9" is cheap, super strong, and fairly easy to find parts for. There's some nice parts on eBay for the swap, or you can go to the Moser website and get a complete 9" ready to bolt in. For a big block I would get a bigger driveshaft, I actually broke mine once.
@NOTORIOUSCARCLUB I actually just found some adapter plates on eBay so I'm using the stock smallblock frame mounts and saddles. You can find lots of good parts for this conversion on eBay.
@dootchltdltd I'm gonna share a tidbit of information with you. You're and your may sound the same, and look pretty similar, but they do have different meanings believe it or not. Don't tell anyone I told you though, it's a secret!
@mwd92 I get about 18mpg in the city. I've never tried on the highway though. That was one of the big reasons I did this swap. I like to drive my car everyday, and with a carbureted 350 that didn't make as much power I was getting around 8 mpg.
On street tires 13.5 @ 102 mph. Top speed, don't know, had it up 150 mph a few times, it's only at 5,000 rpm too, but the car gets a little floaty at that speed. I'm in the process of changing the cam right now so we'll see what it does after that.
No actually there's just a seam where the firewall meets the floor, and I just bent that up towards the floor a bit. There's actually a good amount of clearance above the trans when everything is sitting right, and I've got good driveshaft angles. I think it's actually easier to remove and install this trans than the TH350.
It's funny because everyone I work with said the same thing, that's why I had to cut the video off there, because that's the exact point I locked the brakes up. I'm hoping to make some cooler videos in the summer.
Well I built mine myself, and it probably still cost me $5,000 in parts to make it work. I would expect if you have the engine, trans, and the Monte, getting a shop to do it would be like $10,000. And I ran mine with 3.73s for 2 years, and just recently 4.10s, which are nicer, but not a whole lot different, if your diff is in good shape, I would leave them in there.
how was the swap cuz i'm seriously want to put my ls1 in a 87 monte carlo ss was it a pain i really want to go this in memory of my 98 camaro z28 that got total in a car accident
There's a few hard parts. But I built this 2 and a half years ago, there's a lot more parts available for the swap than there was when I did it. It is 100% worth the effort, keeping up with a C5 Z06 on the street in a car that looks like mine, that's what it's all about. I modified my frame to fit the oilpan in, but I understand an oilpan from an H2 5.3L fits like it was make for the car. And there are mounting kits available from advance adapters and things like that.
so, what frame changes did you have to make for the mounting? I have an 86 silverado (short wheel) and recently got my hands on a drivetrain from a 07 suburban......thx!
I had to notch a small section from the rear of the cross member to fit the oilpan. But the oilpans are different in the trucks, they are deeper and sit back further. I don't think you'll actually have any issues fitting that in. I have an 81 GMC, and I had looked at doing that swap as well. I ended up just doing a TBI swap cause it's cheaper.
Well I didn't find it too difficult. The one problem is that the oilpan doesn't clear the crossmember, I had to actually cut out about a 4"X8" section from the rear of it, and box it all in, since the oil pan is cast aluminum, and is part of the structural integrity of the block, I didn't want to mess with that, and I had to build my own headers, and the wiring is a bit tricky. Other than that it was pretty straight forward. Although I'm a licensed mechanic.
I've never actually had it on a dyno, but with the few things I've done to it, I figure in the neighborhood of 375 at the flywheel, and a bit over 300 at the wheels. It's still a work in progress.
do you have to have a stick shift for a lt1 engine or can you still use manual.
thanks for your help.
