And the ES/ET motors are a possibility as well... if I understand it right you can use them with the earlier transmissions if you re-drill the early flywheel for larger bolts. You may have to change the exhaust pipes or shorten a torque rod, but nothing major.
EK will fit in this car without mods. Anything else will not. I know only because my 79 had an 83 engine in it and when it blew, we put the EK in it. SO I do know that, without fabrication, nothing else will bolt in. Later, QD.
