Conversion Radiator confusion

I have a 91 YJ 2.5L Manual with the stock Radiator in it right now. I am seeking to put a 350 in place of the 2.5 and I know I am going to need better cooling.
I have seen in catalogs a Radiator made for just such a swap, however they seem very very specific. Such as Jeep with LT1 Manual, or Non LT1, Or Non LT1 manual, or auto? I am confused? What does all that mean. Are the radiator in and outlets in different spots, different sizes?
I know that I am going to have a Manual, behind a 350. Can I go ahead and buy the radiator, selecting one for a non LT1 with an Manual?
And for the record I am not going to go with a Be cool. Wayyy too much money for me to spend.

Re: Conversion Radiator confusion

The LT-1's have a different cooling system - reverse flow so the radiator inlet/outlet will be in different locations. The auto tranny option must be for some sort of built-in tranny cooler.

Why wouldn't you recommend Be Cool? Just curious since they're right down the road from me.

Re: Conversion Radiator confusion

I think you misunderstood me. I would very much like a BE cool. However I don't want to spend the extra $. They are about double what a conversion 3 core is.
What is ment by reverse flow? That seems strange?

Re: Conversion Radiator confusion

I don't know too much about it. Since LT-1 had aluminum heads, the flow was directed thru the heads first. It's a completely different setup that the other SBC. The hose from the water pump goes to the heads, not to the intake manifold like most.

Re: Conversion Radiator confusion

I wondered the same thing a couple of years ago and the best I could figure is that have the cooled water hit the heads first helps with detonation. This makes it possible to have a higher compression, read more horsepower, without detonating. The aluminum heads help dissipate the heat as well. I was looking into doing this to my sbc jeep but didn't want to run a serpentine belt and couldn't find the any info on the conversion and had plenty of other jeep mods to keep me busy.

Re: Conversion Radiator confusion

I didn't want a Griffin or Be Cool for two reasons:

Cost and trying to find a radiator shop to repair an aluminum radiator when I put a tree through it in a po-dunk town.

I went with a four core 350/YJ raditator from MEPCO in UTAH.

works like a champ, excellent fit, half the price of a Be cool or Griffin. you may need two fans to keep a 350 Cool in a YJ. either two electric or a manual and an electric depending on your decisions. you may even be able to bolt on an OEM shroud.

Re: Conversion Radiator confusion

Does MEPCO have a websight with information, and ordering options?
And it seems that the LT1 has a flow through the heads first. But what is different about the actual radiator? Is there a huge difference? Size, inlet, outlet. Man, I thought to my self earlier this week. Maybe this week I will get my SBC radiator. (I am slowly getting all the parts I will need because I can't afford to get them all at once) Who knew finding a rad was going to be so complex. I think maybe I will wait until after I have the motor, and then get a rad that I can assure works.
Thanks for all the help

I believe I always work with Eric. Good guy actually uses there stuff unlike Quadratech and it people. Excellent customer support and service. If your outlets are reversed from a normal 350 then it should be the same as a stock Jeep (problem with Jeep YJ to GM). Then they should be right on with an OEM radiator just have it recored to a 4 core.
