The truck blocks from 1958 onwards were drilled for hydraulic lifters, but all trucks came with mechanical lifters and a mechanical lifter cam.
Hydraulic lifters supposedly should be used with a hydraulic cam.

I would use solid lifters for most applications any way. Just like to keep things simple. A little noise don't bother me. But like I said this was a question from some one and..I did not know. Go figure.

I don't think it is just about the hydraulic ones though. Metallurgy is part science and part craft. If and when vendors get the idea that quality matters it will get better. If vendors can sell what ever they have it won't.
