I'm putting a HO 302 in my 91 grande marquis. I'm told I need an ECM from a lincoln MK VII. There seems to be 2 different ones available, for the Bill Blass or LCS versions of the Mk 7. Which one will work and will the exhaust sensors be compatible with the Mk 7 ECM. Also, I know I have to turn the intake around and make a few ather changes to the motor but is there any other things I might run into? Anybody done this that could help me out? Thanks!
