Hmm... those outer springs resemble the front suspension coils on my daily driver; I'd expect breakage if I used them as valve springs...

Seriously- are the retainers a good (snug) fit in the springs?

I asked this because of the adjacent valve in the photo- the non-concentricity of the retainer with the O.D. of the top of the spring is visible. So the retainer's shoulder must not be a snug fit in the spring I.D. This, in combination with the skimpy retainer O.D. and cross section in that area (considering the extreme loading), would cause me to suspect retainer failure.

Mike,

Your car has progressed quite a lot over the last few years.

Can you talk about what you've used fuel-wise from being a mid nine second
combo to what it is now?

Back in the day with the 477 that was 13.7 cr we ran c14. We tried q16 In 2010 with good results. Still running it now. There are fuels that show more power but they are risky imo.
