IS there any difference between the engine, fuel injection, and wiring on a Impala SS with LT1 and 4L60E vs. the LT1 setup on a camaro or firebird. ANd, if so would it make a swap into a third gen firebird any more difficult.

 

They are basically the same, I am sure. The only differences I can think of is that the f-body's got a better cam and a little more aggressive tuning.

 

Yeah, I was wondering about the same things. I found a '94 Impala LT1 with only 11,700 miles. Complete motor, no acc. or wiring. What's this thing worth, they want $1700.00 for it.

There are a few differences. These may not be completely correct answers since I'm assuming the Impala and Caprice had the same LT1 setup.

-Iron heads
-Different Wiring (firewall connector) probably a few other things too
-Different accessories bracket
-As said earlier, different cam. I believe the Caprice cam has more duration but less lift.
-Different induction system, had a home base intake silencer. Also a half inch smaller induction tube/MAF.
-Different cooling setup(hose routing, bigger rad)
-Camaro 4L60E has tail shaft housing mounting bolts for torque arm, the caprice one does not.


That is all I can think of for now. The caprice/Impala LT1 can be swapped in. Probably close to the same difficulty.

 

I'm using the 95 imp lt1 and before it was installed i read(in different websites) that the frame would need to be cut/bent to allow for the a/c unit. Needless to say i didn't have to cut/bent anything. Today i'm running the a/c with the lines.

Just an FYI...

 

How did you run ac with the impala acc. bracket without any cutting or bending? Tell me more, cause I thought that I would need the corvette braket.

no biggie, after the motor was completely assembled(out on the engine stand) then mounted the T5(completely). Then shoved it all in... one shot. After that I installed to power steering lines, cooling lines, gas, etc. But I should have started with the a/c lines first since I had to take apart the whole right side of the engine bay to install the a/c lines. I'm using a/c lines from a 4th gen. and used new washers. My job has taken me from filling in the a/c with 134a but all the lines and stuff are mounted and the 134a conversion is done.
I don't have pics over my winter project. but it's a dream come true.
In sept it was a 305/700/2:73.... today LT1/T5/3:42(the list is in my sign)... totally sweet and well worth it
