The best set up IMO is in front of the RH head
It's seen here on the Holden 350 Monaro
You need to change a few things to do it
Water pump need to be a long unit
Bottom pulleys changed as well.
it's would be a costly exercise unless you are lucky enough to find the parts here at a good price
I have seen a bracket set that set the alternator high on the RH head
But the 350 set up is sound and standard once fitted
Do u have power steering
