What MPH are the shift points at? My car is 42 and 82 (flooring it in OD/D)

I watch the tach...5000 RPM

.. 5000k? Thought those camers spun more, yeah i prob watch the tach more then I should, but once around 11pm on 169 going home 2 weekends ago i felt like finding the MPH shift points... That was fun!

oh dont be frightend to let those cams spin! the valves wont float like they do on a push rod engine.

how high does the rpm go on the aurora

guys does the auroa over heat alot or did gm put a over sized radiator in it because there is no room in the engine compartment

Hash marks on the tach start at 6100 RPM, the tach ends at 7000.

The aluminum mill of the 4.0L Northstar gets really hot really fast, comes stock with a 180 T-stat, tranny cooler, and a big *** rad. I find while driving it holds 95 degress Celsuis nicely.

man my dad'* 3.0 goes to 8000rpm and 7000 is red line i though
what gives with your 7000 and 6100 red line its a DOHC

why is the gm a grand lower than the ford
come on :?

Your Dad'* 3.0 L Yamaha engine likes to rev. No power below 4000 rpm though. It probably has a lot to do with having 4 valves per cylinder and dual intake runners where the GM motor has only 2 valves and a single intake runner.
Those SHO'* will rev to 8000 rpm stock, where our 3800'* will only go to about 6000 rpm (7000 rpm with mods).
The Aurora has 4 valves per cylinder but it is a larger engine, so no need to rev above 6000.....way more torque than the SHO.

Yep it'* not a ford motor AT ALL. Just Get Yamaha to make a decent engine for the ford.. ROTF...
