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.
