70 dart 318/904/7.25

That's exactly my point. If I wanted to put in another motor right now I would go ahead and buy the 400. I want to know can I build what I have not wait 20weeks and build a motor I don't have.....the whole point of the thread was to build what I have not get a new motor/trans/rear end.
I just posted a 318 build I did for under 500.00 bucks. Read it.
