Magnum 5.2 into early A?

Thanks Jamey. That's pretty close to what I'm considering. I appreciate the info!

Dave - I had a '66 that had a 340/4spd in it and it used the '71 hipos. But I'd also heard they didn't fit earlier cars...lol. I'm still wondering about the Ram Magnum manifolds. Those 273 factory ones are really, really bad.

I have a set of the Ram manifolds that I'm going to try on my car with my swap, I can tell they will flow much better than my 273 manifolds if I can get them to fit. The Rams both exit out of the rear, so I'm not entirely sure how it will work out.
