340 help

I'm trying to get to see them today or tomorrow. Here's what he has

1. 340 block with crank and caps
2. 340 block fresh machine work .030 over with the pistons. No cam no heads no intake

There is a $1000 price difference between the 2.
Is the extra money worth the machine work and pistons?

Or screw that and go la360 or 360magnum?

Whenever I put this engine in my car, it will be the last. Until I blow it up or something. I almost bought a 360 last week but it was locked up like ft Knox.

I know it's my car and I should do what I want. But some opinions are welcome.
