Side by side comparison of Ford's Coyote engine compared to GM's LS-based engine

[FL SAAC]

It's the DOHC

The coyotes block is actually slightly smaller but the heads are just enormous.

Coyote extra long timing chains and cam guides, high rpm engine engine

DOHC more rews, more weight, more size,
and higher center of gravity
vs
OHV lighter,  smaller size and lower center of gravity

Welcome to the world of technology, both great platforms.
