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 |

I’m around 0.038” on stock 2L rods and crank, 96mm pistons, and a 7250 rpm rev limit. I do have valve pockets in the pistons and the valve train to support the rpm.

I do have valve pockets in the pistons and the valve train to support the rpm. That's probably pushing the limit for stock rods. I wonder what the stretch is above 7000 rpm. |
