For what your goals are, solid roller.

You need a decent amount of rpm to make that power. To control the valvetrain (Pontiacs are not the lightest) you will need a decent amount of spring pressure. A solid will allow you to use all the spring pressure you need.

Makes perfect sence to me ^^^^. You're gonna have to wind it up for all that.
I still have trouble discounting the horrors of loosing solid lifter needle bearings on the street after a couple thosand miles. However, the hybrid, tight lash setups don't seem to suffer from that problem.

I know where Warren Ksiez's old SR 455 T/A is now living. It has been running on the street since the late 90's with the same solid roller lifters, and has never lost a needle bearing.

My 7 liter SBF has been running the same EndureX roller lifters for over 5 years and many thousands of miles, no problem with those either (knock on wood!). My lash is .021/.024.

Thought that I would get more power w/a hyd. roller set up of the same lift and duration. Using the rule of thumb of needing about 10-12 more deg. of duration in a solid to equal a hydraulic.
How much are the EndureX solid rollers? Thanks, Mike
