So two of my HLAs went out due to loss of oil from bad pan gasket, so I removed the engine head to replace them. when inspecting the head I've found the sider followers are really worn down, witch brings me to my Q. I want to change to a roller set up, are the rollers in say ranger the same as like the ones from bo-port? Would the ranger roller follows work with my cam, the cam I have is like a clone of an A237 just made by crane cams. I love the benifits to the roller follower but don't like the price of buying them new but if I have to I will Smile

Any Ideas?

I sell complete sets for cheap ($40 shipped). Anyway there is much on this subject if you do a search, but to make a long story short, rollers will not work with a slider cam.

Just wondering why you removed the head to replace a few HLA and followers.

Like Chip said, roller followers will not work with a slider cam.

I had to remove the head because I couldn't get enough room with my spring commpresser to remove some of the followers with the head in then of all things the tool brakes Sad
I did a hole search on turboford but it seem to be a conflict with weather roller followers work with a slider cam, some say it does and others say it doesn't.
But are the rollers from a ranger the same as like the ones as bo-port, esslinger, ect. sells?

Don't know, never bought a set from each vendor, but they will work. I'm using RR rollers for my A237 cam.

why wouldn't a roller follower work with a slider cam, is a roller cam made of a diffrent metel then a slider cam?
I did some more research on roller followers and the older ranger followers are the same as the ones like esslinger sells, don't know if there made of stronger metel but there the same sizes Smile

Some feel that the small "footprint" of the roller causes too much pressure (PSI) on the metal of a slider type cam. The metals used in the two types of cam are different. Roller are cut from billet while sliders can be cast with some kind of lobe hardening. Many of the stock, cast ford cams in the 70 & 80 were induction hardened for the lobe surfaces. Surface hardening is not very thick and once worn through, then the cam wears much faster.
