I, too, would like to know what you are doing about the reservoir. I've already dropped a built 5.3LS into my '70 with an electric fan, and new radiator. To wrap up the cooling system, I either need to mount a reservoir, or figure out how to run without one. Since the factory used them, I thought I should too.

I've already found a 2012 Chevy Cruze coolant reservoir that is much smaller than the factory truck style. Thinking I will use that as it will generally blend in better under the hood. The truck res. is HUGE!!!!!! and ugly!!!!!!

Beautiful work on your vehicle so far! I like that you did not have to trim your frame rails to get the factory exhaust manifolds to clear. I mounted my engine a bit too far forward and ended up having to trim a little bit out of each frame rail in order to drop the motor in with the manifolds already bolted on.
