273's were all solid lifter motors. If he wants to do a small hydraulic swap he will need push rods and a set of hydraulic rockers from a 318. I used a 284-484 Mopar Performance cam in one and it ran pretty good.

Not the 68 and 69 273s, they were all hydraulic. You can run the adjustable rockers, but the stock pushrods won't be the correct length. The easy thing to do is swap to the non-adjustable rockers and corresponding pushrods.

As said need rockers/pushrods. I have some extras you can have for the shipping (I think I have 16 pushrods) & shafts too. That way you can keep the solid rocker/shaft assys together to keep or sell

Dropping in a 318 would be easier.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

You're going to have to change pushrods, but you can keep the cast adjustable rocker arms. Smith Brothers can fix you up with pushrods or you can get them ready-made from Summit or Jeg's.

The stock 273 cam is super mild, even the 4-barrel cam only had 248 degrees duration. If it's an otherwise stock 273, the factory 340 cam is plenty big and will be a big improvement in performance.
You friend can either swap in 318/340/360 pushrods and non-adjustable rocker arms, or keep his adjustable rockers and just buy some pushrods ready-made for a hydraulic cam and adjustable rockers (which would be my choice).
Other than the pushrod issue, putting a hydraulic cam in an early 273 is no more or less complicated than changing cams in anything else.

Well based on the replies so far, 45 cubes is hard to overcome with a simple cam swap.
I used a 273 hipo solid cam with .500 lift,that thing rocked.
I have used the 273 hipo solid in a few 318s,all 273 valve gear.
if you are going hydro cam/lifters stick a 318 whiplash cam in it.
