I know the difference actually, but I guess my question would be, Is there a reason to use one and not the other?
All of the previous motors I built were all hydraulic, especially the older V8's.
Is there a reason for one verse the other on a 1.6 N/A? Other than being quieter.

well, solid lifters need the valves adjusted, hydro lifters dont need adjustment. and you can turn a few more rpms using a solid lifter head on a gasser engine. our engines dont care, the head is not the limiting factor for rpms, the pump is..

the lobe is different... solid lifter much much longer.. and bigger diameter too..

I believe the valve lift is the same though.

LOL.. hydro lifter is "longer" so i bet it locks up with non hydro cam first..
people regrind solid cams for performance hydro cams due to the extra metal.. will not work.. and a hydro cam in a non hydro head would require some serious shims to make up the differance..
if you broke your hydro cam.. and are looking for a solution.. you can send delta cams in tacoma washington a solid cam to convert into hydro.. 15 years ago it was a 100$ solution..

Thanks for the info. I don't need a new cam or want to change anything, I just wanted to know the difference on these little guys.
I think most SB V8's go with hydro unless it is a serious race engine. Well, most are roller now anyway.
I did notice that when I pulled the lifters, a few of them were in 2 pieces. The top part came away from the skirts.

They all do that! That is the bit held under oil vaccuum that you change to alter valve gap, and is called a shim. Absent in the hydraulic version ;D

Gotcha, yeah, its not really a lifter in the traditional sense.

Cam follower perhaps.

follower, shim...... I guess I am showing my age when I say lifters, not many motors these days are OHV engines.

Rockers, push rods and screw adjusters....
And grease nipples, but that's another story :o
