need more info- compression ratio, gear size, rpm range, head size, plans for use.
flat tappet, roller, solid, hydrollic ?

11.5:1 compression, hydraulic flat tappet, stock heads, planning on daily driver but able to take it to the track if i want. rpm range is idle-5500rpms.

That's pretty high compression for so low of an operating range... What motor and heads do you have?
If you put in a cam with that operating range, you will very likely have pinging problems even with pump premium. You'll need to cam it up a bit for the CR, but then it won't be happy in that operating range. So far I see a mismatch.

oops i read wrong with my heads it is going to be 10.2:1 compression ratio.

I would say the comp cams xe274 hydrallic flat tappet for the most low end torque and a nice lumpy idle, or the xe284, for mid range torque, and a radical idle. This is for earlier style small blocks, non roller cam.

Have you thought about a hydraulic roller or solid roller? If you're building a motor nowadays, it doesn't make sense to stick with a flat tappet unless you have serious budget constraints. You will be leaving power and/or driveability on the table. The rollers make a much more flexible motor, IMO.
