If you have the car there then go for it

you will need the ls1 kit that you get from CRS to shift the starter motor to the other side and I think you need custom headers from them also but you should be able to pay for all those parts easily selling bits off the ss. You will need to find a V8 K frame for the VR also, there are several vn-vs with ls1's in the on the SC forums and I think one guy on here too
