Safe RPM for a 408" Magnum?

Ok here is the QUESTION!

When you raised you shift point. Did it give you a notable BETTER KICK in the PANTS with the shift??????

ANSWER

If YES! The eng has passed its max HP and was losing exceleration when you shifted!

IF NO! You were still in you power band!

"Non" Forged Piston.....i agree with others, your shortening you engs life at them RPM's.

MY 408 has similar compression, Bigger cam but less air flowing stock RHS heads. My ET Gets longer if i shift over 5800 rpm. This was a custom cam also, with the focus on bottom end torque to combat the High altitude i live at (6800 feet) and stockies Torque converter.

My Hyd Roller cam is a .562/.550 lift 243/247 @.050 Duration. ground on a 102 intake center line.
