Gotcha...just wondering...

I think 6500 is about the conventional max for a Hyd valvetrain. Wouldn't want to sustain that speed though, but your bottom end is pretty stout.. I just have a normal 2-bolt main 302 block, Scat Crank and 347 stroker kit so I'm running a CompCams Hyd grind for the 302hypo firing order rather than the 289 firing order....supposed to be more balanced. Heads are Dart Pro1 170s...I have IDA's on mine.

Your firing order is interesting - thanks

What specs did you use on your Cam? How high do you spin the 347?

My hyd roller cam is a CompCams 35-518-8

Specs are .555 - .565 224, 232 and 112 Lobe Separation

I've been known to use the entire 6500rpm...don't spend a lot of time up there, but the webers take it up there quickly.

Have fun!
