2.0 L race engine deck height, How little dare I? Options

[Driver174]

914-4, stock crankshaft, Stock Jugs, H-Beam rods, JE Pistons, 7k redline; how tight can I safely go? I've heard that a deck height of 0.050" is a safe amount. Can I go 0.040" without risking interference issues?

Thanks,
Jim

Not sure if you remember Evan Fullerton, but he ran stock rods to 8000 RPM! I plan to scope the motor (back side of valves and pistons) here pretty soon, just for fun really. I'll let you know if I see anything.

But I have no idea what the deck height measurement was as FAT built the motor (8.6-1 compression on AA 96mm pistons so clearly not pushing any boundaries) and being strictly an AX car it only saw 7500+ for maybe 5 seconds or less a run in 2nd and sometimes 3rd gears. What sorta works for AX, isn't something that will hold together on a track car and it certainly wasn't making power up there, just saved a shift and was faster then banging off the limiter. Truth be told, I just disabled the revlimiter entirely after I got tired of hitting it when it was set to 7500 so I really don't know what it rev'd to as I just held the pedal down until I had to slow down. The tach only is enumerated to 7k so lets just call it high RPM.

I got 2 seasons of AX out of the car before selling it and it still ran great and had maybe 6k street miles on it so it was at least somewhat reliable.
