Why would somone install solid lifters instead of hydraulic ones? Higher revs? Better response?

 

Seems like you answered your own question.

 

ther are lighter and can be revved higher

 

Sounds good to me.

 

Unless you're building a 450+HP motor... then just stay with roller lifters

 

Thats what I'm planning on. Don't ask me for figures, I wont know until it's been built, but I know it's going to be putting the power down on the top half of the rev range.

 

a solid lift cam will make more power than a hyd. cam with identical lift and duration, but they will require more maintaining, and they will make noise.

I only have flat tappets. My 302 didn't come with them there fancy rollers. I assume you mean "hydraulic lifters."

 

Had solid lifters on a cam in a 351W with 0.57" or so of lift and it ran like a bat out of hell. That said, adjusting the valves became tedious, made worse by have to deal with the the stud girdles. To make adjustment a bit less messy, I cut the top off of a set of valve covers..
