LT1 in a 3rd gen

[gbarger]

Hey everyone I am new to this site and also new to LT1's.

I have an '87 Camaro that I am in the process of putting in a LT1 out of wrecked '94 camaro including the T-56 tranny. Does anyone have any advice on some of the issues that I may run into in doing this swap.

I have done a lot of research so far but still have many issues un-answered. One that I have recently discovered is, what radiator to use? use the '94 radiator and create mounts?

I also want to use the rearend out of the '94 since it has disc brakes.

Any way any info would be greatly appreciated.

man head on over to lt1tech.com i think they have section on hybrids and some people that would be of a big help.

For the radiator, most I've seen have gone aftermarket. For the rear, most stick with a thirdgen rear, mainly the 9 bolt BW 'Aussie' rear ends. Decent strength and you don't have to play with rims etc. and the '89 up ones had the PBR and bigger discs of the earlier 1LE rear brakes.

If you were in this area I could likely find you one of those rather quickly as I have one available right now. :lol:

well i do know you will need a different tranny crossmember and motor mounts of course. you can get the crossmember from Skulte Performance Design (SPD), Spohn with the tq arm, or Hawksthirdgenparts.com. sorry if this is already known info. but yes you can reuse your stock rear end although id personally beef it up a little or go with a 9" or 12 bolt for future sakes. im almost sure you can use the stock style radiator possibly just go with an aftermarket one like Griffin or BeCool. if theres anything specific you need to know just ask and ill see if i can help you out.

Delete the AC. . .leaves TONS of room under the hood if it's gone and easier to change plugs then :)

[Transamman25]

I love A/C cuz im from TN where its required .. if the only upside is changing plugs takes 20 extra minutes ? sign me up .. my A/C stays a 25 F and on full during the summer months .. besides it makes for a better looking build keeping the A/C in check. any other thoughts on this ? Ahh radiator question .. head to the aftermarket .. Not only does it look better but its worth the cost not having to make your own brackets that can be supplied to bolt in the aftermarket radiator

Here is a good resource. The engine swap forum on thirdgen.org:

Good luck!

I have a LT4 in a 1987 GTA. The stock radiator in the 3rd gens will work fine to cool if it is in good shape. If it isnt it will blow the tanks right off the side like mine did when i got it running for its break in. Find yourself the Borg Warner Aussie rear end. That is a totally bad ass rear end and will withstand massive power. My GTA came stock with it and its unbreakable even with the LT4 on it. The biggest issue we had was retaining the air conditioner. We spared nothing on our transplant. I have cruise control and Air conditioning along with a sweet VATs system upgrade. The biggest problem I had with the swap was using the vehicle speed sensor and its transplantation from 4th gen onto a 3rd gen.

Actually you can use the rearend out of the 4th Gen, its pretty much a direct swap. (except for the fact that the 4th Gen rearend is 2'' longer on each side) You will also need a proportioning valve for the rear brakes. I was considering this for my 3rd Gen before i bought my 96'.

[yannickleprince]

I read all your posts but my case is a lil bit different. it is a swap of engine and tranny from a 94 corvette 350 LT1 into a 91 camaro V6. Need help about want else do I need to add on the complete motor and tranny to close my project.
I made some research but they are too general.

I have done all what you are wanting to do, any questions just pm me

Did your corvette acsessory mounting brackets come with your motor?
If you had to buy them where did you get them and how much were they?
Thanks

Also, what headers did you use?

[ssean92]

yeah the corvette mouning did come with the engine, I didnt end up using it I was having issues with clearance for some reason, I opted to use the camaro on and not use AC. this car dont see to much road use other then weekends and track so I didnt see a reason to mess with the ac

[BCdawg57]

Really. What were the clearance inssues with?
You wouldnt happen to still have the brackets would you?

[yannickleprince]

IS IT A DIRECT SWAP?

[Red Devil]

No.

[yannickleprince]

What the extra stuff except the complet motor and tranny from 94 corvette?

[ssean92]

all wiring and computer

[five7kid]

Torque arm mount on the transmission tailshaft.

[ssean92]

yeah it is diff then 3rd gen

[five7kid]

Unless you get a crossmember & torque arm from Spohn that connects the torque arm to the crossmember.

[yannickleprince]

which option will save me more money?

[ssean92]

I have a spohn I am selling if you are interested, I payed 120 for it will sell it for 100 shipped, just the cross member not TA

[yannickleprince]

interested but do u have other stuff like dual fan, radiator or the TA to make the shipping cheap?
