I had good luck with the old black ones with blue stripe. 25k miles with a 6700rpm rev limiter that was in my old camaro.

The springs will be used with a tr220 .551" cam.

I already have the springs. They came with the thunder racing cam kits. I heard the new springs had some failures. not sure if its true. Like I said, I had good luck with the old springs so i dunno. Its just a lil scary if the springs break its bye bye motor
