Bald Eagle,
this change is not that difficult if you are truly intent on doing it and are going to be content with the other limitations of the car. I performed a very similar swap on my 35 master back in the early 70s when I changed the 206.
Firstly I suggest that you read the tech notes on this site describing how to swap out a 216 for a 235 blue flame, and this contains a great deal of the information you will need.
The key difference is that your 33 master bell housing is different, ie the bolt pattern is larger. On the 34-36 master, this is the same as a 34 - 47 Pick up. In my case I fitted a bellhousing & matching clutch ec from a 42 216 Pickup & this matched the original 35 gearbox, enabling original rear mount to stay and a minor bracket change for the rubber bellhousing mounts.
At the front, it is going to depend on the age of your blue flame. If it is an early one with front mounts, it will be easy. If not, you will need to get a 216 front plate and swap it as per the tech notes referred to. It is simply a matter of then making some suitable brackets to attach to the front crossmember to move the engine mounts rearward a little.
Once done, you will find the remaining changes minor.
Good luck, Kiwi Chevy
