Thank you, I wondered if it is possible to retain the radiator in its original position and just add a 'push' electric fan? I really want to try and retain the original look with the larger engine.The Cleon engine with the right gearbox and bellhouse is most important.
Engine supports are different.
The gear lever might be different if you hadn´t a 354/HA0 gearbox.
The manifold connection to exhaust is different.
The radiator is different and mounted on the front.
Some supports are different.

Otherwise it could be a pretty doable straight forward job.
