AFCO racing custom radiator with oil cooler. Under 1,000 miles on this too. You'll need to clearance the passengers side a bit to drop it in place (took me 20 minutes with a 3 lb hammer). Nominally 31x19 radiator. Afco rated it at 650 hp.

Any idea how much it weighs? Also, will it fit in a 4th gen?

Not sure on the weight. It might "fit", but the inlet and outlet are likely swapped to the opposite sides of what you'd need for an LS or LT engine (this was for a standard SBC).

Passenger side is the low side for LT1 and LS1.

That's odd. I thought they were backwards for the LT/LS engines. I'll have to double check, but I think that's the same configuration as this radiator.

Reverse cooling does not make the pump pick-up and output ports change, it just changes the flow path through the pump - heads first or block first.

Also, the driver side port is not all the way up to the top on an LT1 due to the airbox running above it. I think they just carried over the design for the LS1.

I knew it didn't require the hose locations to swap, but I was still thinking that they did. Guess there's too much stuff floating around in the old brain these days.

Tequila will wash all that bad stuff out.

I think the Tequila washed out all the good stuff. But it's worth another try!!!

So this WILL fit a 4th gen LS1?

It "might"? That's my best guess. It's actually a little wide for the 3rd gen chassis, so I'm not 100% sure.

I should mention that it has radiator hoses included as well as a 20 psi radiator cap (both with about 600 miles on them). There's also a low water pressure switch installed in the radiator if you wish to use a warning light that will light up if a hose blows off or something bursts (I've seen this on my friends old AIX car...twice).

Kevin - is this a single pass, with in/out on opposite sides? In on drv top, out on pass bottom? Any dents in the fins?

It is a single pass, there are a few dents, though I have a fin straightener and can likely fix any issues.

Kevin - If Todd goes for it we can use the hoses, cap and switch.

Perfect. And it's leaving her tonight and heading your way.

Thanks!
