ls1 into a 95 fbdoy
as far as what is needed to do the swap.....well if you want to do it right it is going to be a lot of work.
i am in the process of doing the same swap(LS1 into a 95 V6 car).
to start with you will need an LS1 K-member and steering rack,pcm and harness, and you will also need to upgrade the fuel system.
this is just a short list of parts you will need, then there is the problem with getting the guages to work.
for my swap i found a wrecked LS1 car and transfered all parts needed to make it a turn key swap (dash, chassis harness and fuel system) the reason i did it this way is because the LS1 pcm and harness will not connect to the existing 95 chassis harness without quite a bit of wiring fabrication. and even after all that the guages still wont work.
