My take on the situation is that Craig has completed more VH45 swaps than probably any other single person has.
I don't really want to get in the middle of this, however Craig sent me some pictures of this particular swap as he was in the middle of it.. What it looks to me (and was indicated to me) is that this person was sick of waiting, regardless of any reason that Craig gave, and just picked the car up as it was. Craig mentioned to me that he has a series of health related issues that prevented him from working on cars for about 2 weeks.. Sorry but if your back is shot, doing an engine swap isnt going to be easy..
Clearly it was in the middle of something, IMO if the person was doing a VH45 swap in a 350Z it probably didnt matter.. My point is, he didnt even give him a chance to finish the car.. IMO, considering that no one to my knowledge has done a VH45 in a 350Z, it is not an easy task and 2-3 months might not be too far fetched.
Most people simply don't understand what its like to do a swap that hasnt been done, or just a swap in general.. This person probably should have just put a turbo kit on the VQ and been done with it..
And of course, this is why only a handful of us can have special cars that have VH45s in them...
