Convert solid to hydraulic lifters 1967 273 2bbl stock

[Dana67Dart]

Hi all,

I have a stock 1967 273 2BBL with the stock solid lifters. I Noticed that the 4BBl HP 273 came with hydraulic lifters. Can hydraulic lifters be used in the solid lifter block without oil passage or other modifications? ( I recognize that the cam would need to be changed)
Thanks

Yes. Hydraulic lifters drop in.

That is good news. Thanks
forgot to ask... push rods and rockers need to be changed as well?

Nope...the 4bbl 273 had solids too, and a hotter cam than the 2bbl, but yes, you can convert to hydro lifters by using all the hydraulic valvetrain parts, ie, hydraulic lifters, pushrods and stamped hydraulic rockers.

And believe it or don't, I put those used solids onto a different used 340 cam, and ran it like that for a couple of years, back in the 80s,I think it as 80s,lol.

All you need is the hydro cam, lifters and hydro/mech pushrods. Keep your rockers. Question is why do you want to convert to hydraulic? Solid in a 273 is a nice sound (or lack of it when they are adjusted).

I think hydros came in 69, the last year of the 273

I also vote keep the adj rockers, they will be much more precise than the stamped stuff

I love my solids. I adjust mine every couple years. (6-8000 miles)

hyd cams came in 1968,for 273. 1967 was last year for solids.

You are 100% correct, it was the 318 that has the hydraulic lifters according to my shop manual

Not sure I will just wanted to know my options.
