aluminum radiator

Hello guys and ladies,
I know this has been beaten to death already, but can't seem to get an answer for my application, even called BeCool. Guy was very nice, and e-mailed me three times, but not completely satisfied with the answer.

I live in SW Florida, and don't drive the non-AC 69 much in the summer. My question is about the 406" SBC based on Dart SHP block, not an original 400 block that I just put in. Been outta town for 2 months, and kinda forgot what you guys recommended to me. The motor should be well over 500hp, and want to go with a decent aluminum radiator that will:

1) cool this motor here in FL
2) bolt right in and have lower shroud mounts allowing me to use factory shroud
3) stay under $300.

Can't seem to get the part numbers of a radiator that will meet all three requirements. Am using thermal clutch and 6-blade fan, and definitely don't want electric fans. Don't like the look at all. Don't care if the aluminum one looks original at all, just want the cooling fit, and price to be right.

Also for my own knowledge, is the 69 core support the same for both small and big block? One last time, suggestion please/

Thanks as always. Appreciate the patience.

Re: aluminum radiator

Oh yes, also would prefer to get it from Summit or JEGS so I have it in two days, but that isn't set in stone.

Thanks again,

Re: aluminum radiator

I've had good luck with the Summit direct fit. Stock shroud & 7 blade clutch fan, but not 500hp. Keeps it @ 180 with a 180 thermostat on a 100 deg day. You need to buy the brackets from Summit for the lower shroud clips.

Re: aluminum radiator

I live in Tampa, have a '67 SS350 w/AC and use the Summit direct fit as described by BPOS. The car doesn't make 500HP, but it does make plenty of power with 0 (zero) heat related issues.

Stock shroud ('69 w/AC because I use the LWP), Summit shroud attachment kit, thermal clutch w/7 blade fan, 195 degree thermostat (per GM).

No worries, ever.

Re: aluminum radiator

Yeah, they got it, Summit aluminum radiator.

But, Be Cool (the makers of $1000 radiator fan kits) were probably not the place I would try for a cheep radiator.

I have a similar radiator to the summit one, its a number of years old and I believe its made my the same company as the summit on. Its never let me down.

Re: aluminum radiator

If your motor is a 500 hp motor, how long can you sit in the driver's seat while it is making 500 hp? 15 seconds?
It takes no more power from your 500 hp motor to move your car down the road that it does from a 200 hp motor, so your cooling needs for average street driving shouldn't be much different.
We used a Summit 380325 radiator in a 450 hp road racer, and the temperatures were consistently less than 190, even after 15km 150 mph sprints at 8000' elevation.
