I did cam/head work on my GenII last summer. I removed the cam with the engine in the Viper. Following Tator's advice:
(1.) I unbolted the engine mounts from the frame
(2.) Unbolted the tranny crossbrace
(3.) Place a jack under the oil pan, lifted until the engine angled up,tranny angled down.
(4.) I loosened (not removed) the engine crossbrace and moved it out of the way to clear the camshaft removal.
(5.) Heads and lifters remove. However, using magnets on the lifters (20), Tator and others have removed the camshaft with heads/lifters installed.
I used an extra long bolt in the camshaft to facilitate removal.
