Horsepower limit for out of the box Edelbrock RPM heads

Exactly. I've been driving a 2000 BMW M5 for the last ten years. It's obviously much more modern technology, but it it's 5.0 liter V8 tops out with 400hp at 6500rpm, but it produces better than 360 lb-ft of torque from 2500-5500 rpm. That motor really can launch that 4000lb car out of the corner with it's 6 speed manual. I'm hoping to find a cam/head combo for my 340 that will emulate that profile and better the numbers. That would make the Cuda a real handful.

In the past decade or so car companies have focused heavily on maximizing torque at all engine speeds, they all advertise "90% of peak torque available from 2000-6500 RPM" or something similar. Modern cars need it considering they're so fat and heavy.

My mom's 2014 300C with the V6 and 8-speed has the same 0-60 times as her older 2009 5.7 Hemi 5-speed. You only notice the difference at freeway speeds when the gearing can't really help anymore. It's a real rocket off the line though I love messing with the local import tuner d-bags they never see it coming lol
