So the only exterior dimensions I could find on the 3.7 were not official. From pace performance a Lq4 truck engine(we know the trock intake is too tall) is 29" long, 24.7 W, and 28" tall. We know these engines fit with a shorter intake(ls). The 3.7L dimensions I found posted were 23" W, so width should work(non-turbo), 23"L,and 29" tall. It does look like a tall engine with the honkin' intake it has on top. If there were some other intake solution then possibly, or if you went with a tall cowl hood. I am not sure what kind of width the turbo's would have.
