An upcoming engine build....and a little game...

[olddog]

With Titanium valves and retainers on a short stroke small block, I honestly thought you were building for at least 10K rpm. So at 7K, I will stick with my original numbers.

I have Edelbrock performer rpm heads. I didn't build the engine so I do not know what was done to them, but I do know the intake port and exhaust ports perfectly match the gaskets. I have assumed the springs are as shipped. I try to keep it under 6K normally, as I want it to last. I did wind it to the rev limit (7K) in 3rd gear to see where it would loose it. It pulled strong all the way without any sign of valve float. Oh yea, it does have aluminum roller rockers. My point, I do not think you need Titanium to get to 7K.

So I'm wondering if there is some learning here for me. Although I know my engine can go to 7K, I have no idea if the springs look like they are about to go into orbit. That longevity thing is the reason I keep it under 6K. So is the reason for the Titanium so the engine can run 7K all day long, day after day, and live a long life?
