Question Battery relocate question

Picking a radiator setup for an upcoming LSx swap into my '69, and trying to decide on something with both hose ports on the passenger side, or split side-to-side. I'm not fond of the idea of a hose snaking across the front of the engine, and it'll be right below the intake as well. Too cluttered.
I've already got a new aluminum rad\fan setup that works great with a small block, but the inlet\outlet are split and there's no trans. cooler fittings.

Can I get away with a remote trans cooler (already mounted in the car now), or is it advisable to have the trans cooling part of the radiator? That's probably personal preference I'm sure.


Thanks

TCI says to trash the radiator trans cooler. Just run a axillary cooler. I guess they find the radiator cooler in the system causes less heat to be removed. I guess.
That's the instruction that came with my new TH400.

That's basically my thought process as well. I haven't had an issue, and why introduce heat from 2 sources to the radiator?
My fan setup is tight so I won't have an issue with it, but I gotta route a house across the front and I wanted to avoid that.

I just wondered if one setup was better for an LS cooling system, or if it's 6 of one and a half dozen of another when it comes to the radiator.

By OE design, the 4th Gens have a drvr side inlet port on the radiator.
HAs tube running across from the engine, but, has elec fans rather than an engine driven fan, so this bridge is crossed.

I'm sure someone out there has a double pass radiator.
I run an external cooler after the radiator cooler. You can never have the trans oil cool enough, nor have I heard/seen a trans failure for too cool of fluid.

You can either swap the radiator, or swap the water pump to one with the upper port on the side you want. Gotta check the GTO drive pulley setup to see what the distance from the block is- the F body, Corvette and truck setups are all different distances, but I'm not sure which one the GTO matches.

On the GTO they both face the passenger side. Not sure on the Corvette.
I've seen where people have used an unGODLY long Silverado upper hose to snake up and around and all the way over to the drivers side. NOT happening. I'd rather it be short and low under the intake if I absolutely have to. I'm just trying to get away with not buying a radiator so I have no choice but to do it that way. Or buy a radiator and lose the rear discs.

I really don't think you can over cool a tranny in the 48 continuous states. Just run the biggest cooler you can fit, heat is the tranny killer.
Mine has been this way since I put the first motor in (13+ years ago) no issues.
I'm looking at using my stock radiator (w/ elect. fans) and an upper hose for a 2005 Silverado which goes across the radiator. But there are plenty of ideas you could use....all depends on your set-up.

Also remember if you want to run the cold air intake like John showed you yesterday, that goes to the driver side, so you'll want the radiator hose on the passenger side ideally.

Yer right Bob, that was my point. My battery is still in the core support so it's gotta go to the drivers side for air.
It just gets cluttered up front there... More decisions!

Move the battery to the trunk....not hard, displaces weight, and cleans things up a whole lot

What I meant was the air intake has to go to the drivers side... not the battery. I'm not in Europe.

And I hear ya Doug...it's always been 'on the list'. I guess I'll need the extra few pounds over the rear now anyway.
We'll see.

Entropy makes a nice LS radiator/fan combo. About $700. Although if you have a good setup now I would get creative with the radiator hose routing. Maybe some polished tube with silicon couplings.

Spectre makes 69 intakes for both pass and drivers side.

You could move battery to trunk and go that way.

If you go trunk mount battery I suggest you run a solenoid in the trunk so the battery cable is only hot when starting.

I like the thought of a dual-fan setup like the donor car had... two fans, two different temperature thresholds. If he'll let me score that stuff cheaply I'd like to try to fab it up.

We would never let him do it any other way.
