e58 police oil cooler

yes for towing, hard working truck, motorhome, south west us oil temp gauge will tell
if you are asking about a cam there are several recent threads
which chamber (flat deck or recess) in the edelbrock heads and cc's (are they stock or ported) cast iron 340 manifolds, 360 manifolds, headers, what size and style
what pistons and compression height and deck clearance, what gasket do you plan on
what gears
I'd get a tranny cooler B 4 an engine oil cooler 340 higher stall converter or 318 lower stall converter (diameter)
is this a cast crank late motor or an earlier forged crank one?
as old as all this old iron is if you have not owned it since new research all the details
get all the details together and you will get an overwhelming amount of cam suggestions
if you are already looking at catalog/ shelf grinds start with Lunati Voodoo and Howard with the "15" footnote but exhaust ill make a difference
