LM7 Cooling Hi Guys, I am busy installing a 5.3L V8 Vortec engine into a Range Rover Classic which is my dune toy here is SA. Because we don't have these engines in production vehicles here, info is rather limited. Hence, I would appreciate some advice.
I have 700mm x 400mm to build a radiator. Will probably make up a 50mm thick Alu radiator. Will this be big enough? What size radiators do they run on in standard form?
Here are some points to consider:
1) I have had to remove the viscous fan and will be fitting electric fans
2) I Also want to fit an oil cooler.
3) this engine will work hard and under constant stress. It's a toy...

The stock 2 core aluminum radiator for a Silverado with 5.3 is about 34" x 18" x 1 1/4". Sorry, you'll have to do the metric conversion.
Your radiator manufacturer should have an approximate hp level it will cool.

A factory truck with this engine stock uses dimensions are 436.56mm tall and 717.55mm wide. That is tank to tank from what I can see, so I would assume an aluminum radiator with at your dimensions should suffice, with proper fans of course.
I would imagine that make an upgraded aluminum radiator for the Rover, I feel like that should suffice just as well and take out some guessing on fitment.

Part identification Can someone perhaps identify this part? It seems to be some type of fuel heater? Connected to the exhaust manifold & intake manifold.
Can it be removed? Otherwise I will need to accommodate it in the new exhaust headers
