i just purchased my 95 camaro and no it has a rebuilt motor and trans i know it is cammed but i was told it is bored and stroked to be the same ci as a ls3 so it should be 375 has anyone heard someone doin that to an lt1? and if so what is needed to get it to that point rods heads pistons????

thanks art

 

Well besides the ls3 having an aluminum block..urs should be cast iron

1993 camaro "superzee" z28

 

yeah i know that the ls3 is aluminum im just curious about displacment and if anyones heard of a 375ci lt1 and what parts are required to get it to that point I plan on calling the shop on thursday but i dont know how much help they will be

thanks art

 

I have never seen a 376ci LT1 but I've haven't been around these cars as long as a lot of people here have been so they might have.

 

If you combine a 3.75" stroke crank with the stock 4.00" bore, you will have a "377". Question is - why is this important? You can build an LT1 anywhere from 355ci to 396ci, or even 409, 421 or 427ci (with sleeves). The fact that it might have the same displacement as an LS3, which has not even the most remote relationship to an LT1 would seem to be insignificant.

 

I think the op was asking more out of curiosity then relating to an ls3. Im sure being he has never heard of an lt1 with that ci he might have been skeptical about the build.

yeah i only used the ls3 as an example the person i bought the car from isnt the most reliable person and im only wondering whats required so when i call the shop tommorrow i have the most information at my disposal as possible.

thanks art

 

aren't 377s de-stroked 400s?(high revers)
I remember having an old 400 block in my garage and a 350 crank oversized bearings and the whole nine I got off the recycler back in the day... lol I never got around to building it

 

You could use a 3.625" stroke crank, and bore it to 4.060 and end up with 376ci (LS3 is 376.05) but I haven't seen anyone do that setup with an LT1.
