AND have NO rear axle diff banging to bed issues?? those that have C notched your rear axle, can you post your pictures. thanks

He'll want 3" of clearance for a trouble free driving experience. 2" would get him by but it could occasionally make contact. Anything less than 2" is going to make contact sooner or later.
The more the frame gets notched, the weaker it gets so keep that in mind. Typical 'bolt-in' c-notches that remove 2/3 of the rail height are weaker than the stock rail despite having a thicker vertical area. Just welding in a 'C' (half pipe) is not as strong either. Like Ziegelsteinfaust suggested, if more than a 1/3 of the rail height is removed, the frame should be reinforced above the rail in some form/fashion.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
