I am considering using the Skunk2 Pro3 cams in my motor but don't know if the Supertech springs/retainers can handle the lift and duration of the Pro3's. I use the H1002D springs and retainers presently and I need to know if the will hold or not. Has anyone used these cams on this valvetrain?

 

You're need the SPR-H1000DR for the PRO3s. I'm running those with my PRO2s as recommended by Tom at Portflow.

I have the Toda D's on top of the SPR-H100DR, handles til 10.5K no problem

 

Why not just get the Skunk Pro springs and do it right.

 

The Pro springs/retainers are a little out of my wallet range right now Don.

 

I am running PRO3's with Supertech springs and alum retainers.

 

Ran BC5's, Pro2's and now Pro3's all on the Supertech DR's.
