As above i have got a 1.2 nova with a knakered head gasget,and i also have a 1.6 cav on a j plate what sort of things do i need to drop it into the nova,what shafts do i need and do i need to do any wiring. What do u think?
It depends on what engine's in the Cav. If it's a 1.6 carb, it'll be plain sailing putting it in, as there'll be no extra wiring to mess around with for an injection system and no need for an injection pump/tank (your existing setup would be fine).
If it is an injection engine, it'll no doubt be SPi, in which case, all that messing around with extra wiring/injection pumps and tanks etc probably won't be worth it because the SPi systems are pretty poor to say the least.
As for the shafts situation, you can use your own driveshafts no probs
