Quick 4.8 / 5.3 question

[hotrodtim]

I just found this portion of the forums and suspect that I could probably find answers to my questions if I looked long and hard enough. Unfortunately, I am limited on time and need an answer asap. I purchased a 5.3 out of a 2005 1/2 ton Chevrolet pickup for my 1951 Chevrolet pickup build. Unfortunately, it was just a long block and doesn't have much in the way of accessories such as water pump, brackets, alternator etc... I found a very low mile 4.8 out of a 2002 1/2 ton Chevrolet that is complete including the L460E transmission I want to use. I know the block is the same for both engines and that the transmission off the 4.8 will bolt up to the 5.3 just fine. I'm just not sure about the other external accessories that I want to use on the 5.3. Also, the 4.8 and L460E have been sitting in a guy's garage for about eight years so I'm a little concerned about that aspect. Any thoughts/input would be appreciated, I need to try to make a decision on the purchase this weekend. I can get the motor/transmission on a trade so I'm really hoping it works out.

Thanks guys,

Tim
