Shouldn't be that much harder than a standard longitudinal setup with a BOP adapter. Sure would be cool.

you do know that the LS1 shares no common parts with previous small blocks right? even the bellhousing pattern is different

not that I am aware of, howeevr LS1SWAP has posted in Tech, a thread on how to swap in an LS! with full deatils. Excellant reading I must say.

That would be cool..... Don't know what clearance issues their might be. I am surprised others haven't followed me and Orville.... Especially now that I have figured a way for a smaller flywheel.

what are the advantages of going longitudinal?
why not just put one in the normal way?

Two big ones...

First one is more space around the engine, better cooling, etc.

Second one is most longitudal transaxles have a lot more strength than transverse transaxles...

Porsche transaxles for example...

I don' think an LS1 would be any harder to do than a first gen SBC, the main reason I am using a SBC is the cost factor. Doing the longitudinal swap is expensive to begin with and there is alot of fabrication also, I am trying to limit spending by going with more common (read cheaper) SBC parts.

One of the major downsides is that, according to measurements I took several years ago, the forward ends of the cylinder heads would protrude into the passenger compartment by more than 13". Pile a couple of cement blocks up on your console appox. 15" from the rear window to see how handy it would be to have the engine at your elbows.

This guy tried with an Audi 5000 trans & gave up, although others have picked up the torch:

Archie, I was assuming they meant taking the trunk out

Yes, I did mean taking the trunk out.

As for the engines being different everyone knows that. It isn't very hard to put a LS1 on a normal tranny though.

Well, then my two reasons are still the main ones

Seriously now, haha

my reasons would be based on performance vs. investment. "i" couldnt do a ls1 that would out perform a standard v8 swap for the same amount money. unless you get a sweet deal on a ls1 and more important, all its componates a good ls1 wouldnt be a wise choice for me. sure it would look cool, but a dollar is a dollar. but i would like to see someone do it!

The only way that taking the trunk out would help you is if you were going to turn the engine/trans around and have it hang out the back of the car. Or if you are going to use the extra space provided by removing the trunk to move the rear axle centerline back thus stretching the wheelbase. If you are going to mount the engine in front of the axle centerline then not only do you have to have enough room for the length of the engine, you also need to account for the length of the transmission that is in front of the axle centerline.

Thanks kameo, I have to clean the screen off now.

I think Dennis was referring to the Toronado transaxle based longitudinal swap when he started this thread. Note that he said:

quote Originally posted by dennis_6: ...with a BOP adapter...

With the Eldorado/Toronado based swap, the engine would be just like cardealer's, and as he pointed out the adapter plate can be done. It's just a matter of who wants to build the more expensive LS1.

The advantage of course is you get a light all-aluminum motor, with great performance and efficiency, and with the removal of the trunk, etc, might be really close to the stock weight. Mount it reversed like cardealer and it would barely affect weight distribution.

perk

Exactly perk.

I don't think the LS1 is that much more. The engine itself is more, but after some of the new findings I have come up with. I think the install should be easier than an LT1. I know I have always said I wouldn't do installs, but if anyone is really interested give me a PM. I want to do another one now. If not for me, for someone else.

sorry bout your screen but here's the link

Are Toronado transaxle hard to find in good running order? About how much are they going for? And how hard would it be to mount it to the frame and to the motor? I don't know I'm just asking.
