I've always loved the Fox. I'm sure if you look you could find plenty of pre-93 Fox's at a reasonable price.

I was NOT a fan of the SN95's when they first came out, and they still take a while to grow on me, but if they're done right, they can look pretty good. I just don't like the fact of the lowered horsepower with increased weight.

If it were me, it would be Fox all the way. No and's, if's, or but's about it.

As far as the hypereutectic pistons: that's still open for debate. There are guys running modular motors with hyper's pushing insane amounts of boost and running insane track times.

It's true that hypereutectics are weaker than forged pistons and don't hold up to detonation well, but they also have decreased thermal expansion and thus can be run to tighter clearances. Also, most major engine failures involved with hypereutectic pistons would have caused similar damage even if the motor was equiped with forged pistons.

I'm running Keith Black pistons right now, and I have no problems. However, according to the ring-gapping charts provided by the manufacturer, I would likely need to increase my ring gap to safely run nitrous.

Maybe I'll try a little 75 shot with conservative tuning and see what happens....
