Looks sweet!

Depends on how fast you're tryin' to go.

General rule of thumb is 12.0 secs in 1/4 takes 400hp. With the engine you have that's no problem.

You trans will need to be strengthened. I don't know how strong you race 10 bolt is, but most recommend going to a 12 bolt.

Add to that sub-frame connectors, steering rack brace, and some brakes and you should be set.

Wish I had it that easy...

 

A 427 would be killer in a third gen. You would need to do some frame and susupension work to make sure all that grunt doesn't twist you Z into a pretzel!!

I would go for the 427 if it were me. Even if you drive everyday or couple times a week, I think it would be fine. I don't know about the swap though, never put a big block into a third gen.

Good luck...
