I thought about going with a regular flat tappet for my 440 build in my 71' Roadrunner, but recently have some added funds. Going to be buying from Lunati as I used one of their cams in a small block chevy with awesome results.

My questions are what are the big benefits to having a roller cam? Which is better: solid or hydraulic roller? Do you have to adjust the valvetrain the same with a solid roller like you do a solid tappet?

My engine build consists of:

-1978 RV Block .030 over
-Flat top six pack replacement pistons (L2355)
-Ported 452 Heads (2.14/1.81 valves)
-EZ EFI System
-Headman Elite Headers
-All updated ignition (EFI Needs it)

-4 speed car with 3.55 or 3.91 gears
