Subscribing... Im hoping to maybe swap over to an LS3 sometime next yr.

We've used the PRC units with great success and the price is very reasonable. You can get dual 11 or 12" fans.

You can go with a C&R but you looking at $600 - $700 for just the rad and then you need fans....

I have a friend that uses an Entropy on his LS powered 1st gen Nova. Has had no problems and he drives the snot out of it.

PRC radiator, 2 12" fans, 500 HP BBC, 108 degrees in Phoenix driving in traffic. Engine temp b/w 190-210

I used a Entropy in my 69 LS1 and it worked GREAT. The plastic cover for the fan was crack and they sent a replacement out ASAP along with a tool to fix it. Great customer service!!

I have run at least 30 Entropy radiators- usually in big block and LS powered cars with AC and in 100 degree Sacramento heat, in daily drivers.
I have had no problems whatsoever. They can accommodate the steam tube for the LS and put the inlet & outlet on the same side. SPAL fans move a lot of CFM.

Great value, solid product and excellent customer service in my book!
Tony has been really helpful.

If you need any pics, pricing or feedback, give us (or Entropy) a holler.

Which of these radiators use the thinnest fans? I want to turbo eventually and will need all the room I can get.

Entropy offers a thin-line SPAL fan combo. Most manufacturers can accommodate such a request, just be sure to calculate plenty of cfm!
