64 valiant wagon-5.7 hemi

Does anybody know if you can even install a 5.7 into an early a body with the stock k frame and manual steering? The tti mounts say 67 and up.
I have a 5.7 in a 63, but I'm using an AlterK. I don't see any reason you couldn't do it with a stock K frame. I used Jeep srt8 exhaust manifolds for clearance and price.
