Got the Hemi in the Winni. Fits great!! the only issue is the lower rear pass a arm mount is right where the starter is. Its not to far from fitting though. Ive planned on making the mount removable there so that the engine would drop out the bottom... I fabbed all the suspension around the original 318... I know ....

What transmission are you using?
@Blake Andermann I believe Nag 1? It's out of a 2007 chrysler 300
Do you have room on the opposite side of the engine? Jeep NAG1 transmissions had the starter on the opposite side just like the 318. You can buy just the jeep bellhousing for a NAG1 and switch to LH mounted starter
Well the drivers a arm is in the exact same position on that side so if the starter is the same then it won't fit any better. But is it the same starter as mine? I would thinknif it was then the starter would be mounted upside down from thw way it is on mine and that would probably work
