I have always heard that solid lifters make a whole lot of noise and have specific cams that are made for them, maybe I'm off though. If they are loud, then it might cause false knock.
But like I said, could be completely off.....going from a memory over 6 years ago.

My guess is that you or your friends are Chevy guys!
Solid lifters are not normally used in Stock Buick motors for a few reasons. First, a flat tappet hydraulic can easily reach 6000 RPM which is about the peak of the power curve. if you have a fairly modified motor, a hydraulic roller cam can take it higher.
Solids require an adjustable valve train and constant maintance.
If you want max power at 8000+ RPM in a stage block, then a solid, flat or roller, will take you there for a while!
Do that with a stock block and doubt that it would be whole for very long?
So I guess your answer is a Buick motor develops near max torque at a relatively low RPM and keeps it there over most of it's power band. No need, or improvement, using a solid set up in that case especially if street driven.
