Fords lower gear ratios in the Mustang make perfect sense and i highly doubt you'll call those ratios insane when the Camaro gets them next year.

Stock Coyote airflow
Known stock Coyote intake port head flow numbers are 289.4-cfm intake and 201.4-cfm exhaust at .500 inch,

Lt1 airflow
Lift---Intake (cfm)---Exhaust (cfm)
0.100
0.200 151 111
0.300 208 152
0.400 256 174
0.500 294 183
0.600 316 189

so it appears the Mustang might see better port velocity and of course higher rpm capability due to overhead cams where the Camaro has more airflow and bigger CI.
Funny you choose to respond to me and say nothing of all the fail in his posts

The Camaro will never get a 3.55 rear gear. And likely not even a 3.15. It is in fact insane gearing compared to the Camaro. But again you respond to me and leave your troll friend out of it? Cool man

Let’s see ford make 460 hp out of a 302 16 valve pushrod motor in today’s market. No way no how. The dohc 32 valve setup is an advantage just like the cubes in an lt1. Nut hugging one or the other to claim victory is equally ignorant
