I hope it's a pushrod.Nice run, good 60', sorry to hear about the pushrod.
I'm not sure what the rpm is limited at on the shifts but I broke traction on my second run rpms spiked a little. I think that is when it bent. I'm sure cam, springs, and 40+psi of boost didn't help either. I need better tuning also.I ran stock push rods in my built motor without a problem, but I didn't run crazy high RPM in it either. I think I shifted at around 4000-4200 RPM.
