I am currently planning on a LS swap into a 83-88 Monte Carlo SS. This project has some time before it is started but I want to do my homwork and get a budget in place. I think I have decided on a LQ4, L92 heads, & a LS3 intake. I was curious was there any advantage to get a LQ9 over the LQ4 and if I can get the motor complete is there anything that i can reuse to cut costs? Obviously I am looking to do fuel injection so I know I will need a wiring harness and PCM.
