It's not the physical dimensions that are the problems, it's the electronics. Getting the correct computers and making everything to talk to each other is way more difficult than just bolting everything in.

Why not just get a performance rebuilt 2V motor (approx 340hp) it will bolt in and hook up just like your old motor.

Have to agree with everything he said! The built 5.4 2V will probably be cheaper in the end than than trying to retrofit all the electronics too.
