Spotted this close to me and wondered what the possibilities are?
(of course they are endless, but realistically...)

I have a '66 425/400 sitting in the garage and just didn't know how close the mounts for that would be to the current 330 in the vehicle as it sits right now.

Any insight on if this would be a nightmare to convert over, or if it might be a reasonably painless bolt in.

I know that since it's already a conversion from the original engine, there may be god-knows-what previously done to the engine bay, but if the 330 mounts are similar enough to the 425, it may not be too difficult.

Just thought I would see if anyone here has any ideas/insight before I make a trip to go check it out.

Thanks!

If the 330 is in there correctly I would guess the 425 would be an easy almost direct swap. The T350 trans will work behind the 455 if driven normally.

 

The 425 will bolt right in. The problem is the trans. The T-350 will be just fine, the T-400 is longer. In that kind of swap they had to make a trans cross member. That car has an X-frame in the middle and I'm positive they made something to fit in the X . With the T-400 you would have to remake the cross member.
The exhaust will pose some what of a problem, but the exhaust shop can take care of that.
If they did a clean job, it should be no problem. Your best bet is to go look at it and decide what you can do with it.
Looks like there may be some wiring issues under the hood.
