Hello all, I have a few questions regarding the straight 6 engine for my 67 mustang coupe. I was originally planning on hopping up my suspension and going with a 302 engine. I have decided though to devote most of my money towards the beautification of the interior and exterior, rather than focusing on speed off the line. Some questions though are as follows. Any and all help is greatly appreciated, and most welcome.

1) Can anyone recommend a site that has rebuilt straight 6 cylinder engines?
2) Are there any websites that specialize in chrome, fancy, performance parts for the straight 6 engine?
3) How difficult is it to change out the manual trans I have now for an automatic, keeping the same straight 6 engine?
4) My mustang did not come with air conditioning, how hard would it be to install this? Any site suggestions?
5) How do I tell what size straight 6 engine I have?

I am new to this, so please do not mistake my lack of knowledge for ignorance... Thank you again very much!

 

I am guessing that the "Classic Mustangs" section on this site would be able to help you more than this section. This is almost all newer mustangs in this section.

The motor in your Mustang should be a 200cid L6
