Great answers so far people... NOT!!!! :lmao:

A solid cam, uses a solid lifter. Its pretty much just a round hollow chuck of metal. The lifter rides on the cam lobe and the cam lobe moves lifter up and down. A solid cam needs a lash setting, a space between rocker arm and valve stem

A hyd cam uses a lifter that is like above but also has a spring and plunger inside it. The lifter fills with oil and pumps up. On adjustment, no slack or space is needed between the rocker and valve stem as the lifter bleeds off and pumps up with oil to chusion the valve train.

Solid cams do not "hit harder" or run rougher then a hyd cam. The cam duration and LSA is what causes a cam to sound wild or mild. Both a solid and hyd. will and can sound rough or smooth based on the size of it.

Yes a solid cam is louder running. It has a noticeable click. Kind of sounds like a sewing machine running, again thats due to the slack in the lash adjustment

The main problem with most solid lifter cams are their power bands are usually high RPM, because they're designed to rev very high for racing applications. Most production solid cams have lots of overlap, so they're piss poor for pulling vacuum, and if you're running accessories or have an automatic trans, can be a problem.

Hydraulic roller cams are much better suited for street/strip application, allow for fairly high RPM, and you don't have to worry about adjusting valves at all. Plus, they're friendly for engines running accessories, especially stuff dependant on engine vacuum.

Hope this helps a little.... :D

Cams come in stages and I have a stage 1 as I'm on lpg
LOL....

The difference cant be basically spelt out as to what type of lifters they use. Hydrualic use hydraulic lifters and solid use solid.
There are pros and cons to each camshaft. Solid are good for making more power and revs to a degree. The cons are they're noisy, u need adjustable rockere and the clearances need adjusting fairly regulary.

Hydrualic cam's are quieter more "street" friendly as in they're usually easier to cope with everyday. your clearances are compensated for by your the oil flowing into your lifter that the valvetrain is maintenance Free compared to a solid setup. Theres Potential to make decent power on these.

As for your other part of the question yes you can get both types for a 202

Hydraulic.

Honestly mate, for a street engine, stay with hydraulic. For a strong street/race engine then go solid for sure.

Crow cams or wade cams are both in melbourne and sell cams to suit price would be anywhere between 100-$300 id say depending on cam specs and material
