I knew you guys would like this subject !

Yes, short stroke... VERY quick revving.
Phil, it IS good to 7000..... it's the 7400 that it saw on my fastest qualifying run... which BTW, seems to be a pattern. The higher RPM range DEFINITELY had the car going better speed and ET ( though 7400 was NOT deliberate ! ).

If I shorten duration, and / or advance the cam, I'll have to rely on this thing becoming a mid-range torque monster, in order to achieve that elusive 125 MPH. It won't do it.
Paul, when we went back to back on the dyno, and the cam was retarded 4 degrees, the engine torque curve moved up, but didn't change numbers. Peak HP jump by 18, and the engine hung at peak HP through 6700 RPM. It doesn't lay down... and I LIKE THAT ! ! ! !

My cam may be a little "out there" already, Alan ?
264 / 272 @ .050", on a 108.
I've contacted Ferrea a few times about making valves for me.... they flat out REFUSE.
2.20" / 1.735", but about .100" / .125" shorter than BBC.
Spring installed height is also much shorter than BBC... it's basically the same as small block. My current spring was Comp's strongest beehive, with a 11 gram tool steel retainer. Shimmed stffer on the intake, the spring was almost stacked.

At this point now, I'm willing to give up 10 potential HP, by using a softer ramp intake lobe. Due to recurring disasters, this engine's cylinders are right at ..074"- 075" over.
In addition to this, due to multiple repairs, and grinding that has gone on with these heads, they would no longer pass tech. I have another pair of virgin large port castings... actually they are the "better" 583 's. I don't want to take chances with the them.
