If someone has the desire for higher revs and has sorted out solid lifters, stronger chains, cams heads and intake, what is the next limiting factor? Piston speed with stock stroke doesn't seem too crazy for 10K+
I have seen on the web CNC'd heads that flow 400cfm+ for LT5. I believe that would not limit rpm's to below 10K.

Turbos are definetily easier, but they have their own problems to deal with. Too bad LT5 is dead in terms of engine development.

Titanium valves have very little fat and will give some extra float protection. I was personally looking at an incomplete set on Ebay a while back. Also, beehive springs from compcams look like they will fit with no problems. Zomething to think about.
