[750hp]

In the interest of not threadjacking Berm's question, but still considering less expensive solutions to fix my solid roller concerns...

I have a supercharged 9.5" SVO block stroker with a 660 lift solid roller cam and 320lb seat pressure springs.
It's out of the car at the moment, and I'm going to check bores/rings/bearings while it's out.
I've been worried about friends destroying their SBF motors from rollers breaking off and jamming sideways in the lifter bore, damaging the block, rods, etc, etc. Another had a complete failure of a new set of rollers in his 2000 mile old 351W
Can the solid roller cam stay, and just the solid roller lifters be replaced by hydraulic roller lifters?
Are pushrod lengths the same from solid to hyd rollers?
Are the springs too stiff for a hyd rollers?

If I can replace the lifters with hydraulic rollers without changing the entire valvetrain, I'm there!

Thanks for your help.
