redline?

[stock93]

Can anyone tell me what the redline is for the 3100 and the 3.4 dohc engines? 3100 with roller rockers redline as well.
I've searched and didnt find it. Also what can be gained in rpm by swapping springs, etc. 3100 with roller rockers redline as well.

Thanks
John

Mechanically the engine is good to 7000. The spring however float around 6500. DOHC would be a little higher.

No advantage will come with swapping in stiffer springs unless you swap in a better cam.

there is no point in revving the stock 3100 over 5400 RPM cause it ain't gonna make more power.
