2JZ VVT engine swap in an Early A Body?

I'd dig the swap. I debated doing a 1JZ or 2JZ in my Dart. I believe someone here put an RB25DET in a '67 Barracuda. The only thing that put me off with those swaps is the weight of those straight 6's. They're as heavy as a small block.
And those rbs if you don’t get the correct stamping they crack between 4-5 on the wall. Doesn’t hurt anything but I’m not paying another grand for a special block. That immediately turned me off of the rbs. Great engine....but the castings determines how hard you can go and at 500 you have no choice but to crack that bottom end open and start upgrading things..... I want plug and boost and go
