Why the hell is erryone so scared to spin past 7k with these engines? That test included. To me they dropped the ball bigtime on that test.
Typically when you go to the effort to change a cam you're also looking to extend the rpm range.....if you're not then you're doin it wrong. That allows you to take advantage of making torque through gear multiplication. Example
3.73gear x 400tq = 1492
4.10gear x 400tq = 1640
Now taking that into consideration you can lose about 35tq in that scenario and still have 1492tq with 4.10. So typically you're not losing any tq that accelerates you with 4.10 and 365tq. So if you utilize being able to rev to 7500-7800 with these intakes that run to higher rpm your over all gain will be there. .....even at low rpms like some is concerned about.
