4.7 rev limiter? (2002)

In other words the fuel is restricted to hold the engine at a predetermined RPM.
So you can run it up to red line, push in the clutch and the engine won't over-rev when you shift. Has anyone power shifted a 4.7 5-speed? The last time I power shifted a car was in 1966 when I had a Chevelle SS with a 327. You just had to be fast so it didn't over-rev back then.

i have powershifted it and it doesn't overrev... also, the max hp is made at 4800 rpms and going much higher than that doesn't really help out the truck at all... i usually shift at around 5k and let up on the accelerator so that the engine drops rpms a bit and i don't tear up my clutch or rear diff too bad (i desintigrated the rear diff LSD clutch pack doing a powershift into second so i try not to do it too often)
check out my youtube videos and you can see how i do it...

Always shift at redline for maximum acceleration! Unless you drive a vehicle with an extremely narrow torque band, the advantage of a lower gear will always outweigh the diminished high RPM torque.
Redline in 2nd is still putting a significantly larger twist to the rear wheels than 4800 RPM or what have you in 3th.

EDIT: and loud, how the **** does your truck get up to 6200 rpms? mine cuts off at like 5500 (where the engine won't go any faster)
