Since the hood opening on all Cobras are about the same size it is probably the same job installing an engine in any Cobra.
I have had my engines in and out so many times I have lost count.
Here are a few tips. After you have done all the under car disconnecting, raise the rear of the car as high as the jackstands allow. Remove the front wheels and lower the front of the car as low as you can while still leaving room for the legs of the engine hoist to fit under the chassis.
Install engine and trans as one unit with starter and clutch slave already installed. (put dummie yoke in trans to keep from losing gear
oil)
Lay towel over trans so as to not scratch engine compartment on the way in.
position floor jack under car in area of trans to assist in leveling of unit.
I just reinstalled my engine last week by myself (don't need an audience) in about 1/2 hour using above method.
That 1/2 hour is to just get engine in car, another few hours to get it all buttoned up.
Hope this helps,
