90° DOHC adds significant width. Here you can see that Coyote is about 4" wider than LT1 which is not a small difference.
There is a reason why people LS swap everything, but not Coyote swap. The DOHC V8 is simply too wide to fit into engine bays originally designed for I4 engines.
To help you visualize, these are BRZ/FR-S/86 fitted with Coyote and LS engines. The only reason the Coyote fits at all is because the Toyobaru Twin comes with a wide flat-4 engine stock.
 
If anything, I think the LT6 would be even wider than Coyote, particularly with the exhaust manifold. Remember that the MR layout gives the C8 a lot of engine bay space to work with, so size constraint isn't exactly a high priority. |
You’d have to look and see comments GM may have made on the Blackwing V8. My recollection was the smaller Blackwing would not fit in Alpha.
As for the V6, that’s 60 degrees while a V8 is 90 which would make it wider.
