I hunted around a little, I used the 6.1L Hemi for my search, since the 6.4L isn't bigger dimensionally (the Hellcat is proably a smidge taller, but the SRT's have a "high rise intake" to begin with, so it may break even). All I found was 42"L x 42"W x 48"H and a weight of 149lbs. That 4' height is a killer in such a low car, but that is with the stock oil pan and stock intake manifold (a dry sump oil system and different intake manifold would make it shorter). Also the 42"L x 42"W is without any accessories besides the water pump (integrated into timing cover).

IDK how I know...
Also... for a N/A engine (10.1:1 CR) that isn't "Built for boost"... on 6psi it went from 375whp (with intake, catback and tune) to 527whp (S/C, same catback, base tune).
