74' Scamp

Hi all,

I wanted to ask your opinions about a car I'm thinking about buying. It's a 74' Scamp with a slant 6 77,000 original miles. It has always been garage parked, no accidents and some minor surface rust on one rear quarter panel. The asking price is $4000 CAD. I have a 440 that a friend gave me that I would like to rebuild into a 375-400 hp motor 727auto 3.55 gears 2500 stall. Two questions before I continue with this pursuit. 1. Does this seem like a reasonable price for the Scamp, 2. Can I get some decent headers on the 440 in this body? I am a Welder by trade so I've got the know how when it comes to custom fabrication, just would like to get some opinions on what would need to get done for this to happen. Thanks.
