In Be cools catalog, it says the small block radiator they offer will handle up to 400 hp with fans. I have a 383 that makes 580hp at the flywheel, and need the proper radiator that will fit with the stock clutch fan. If I have to go to a BB radiator and shroud, will the shroud be too high/low, to far left or right for the small block fan? And what hoses do you use? SB or BB?

troubled and frustrated..........

i am using a Griffen large core radiator,they make 2 core sizes,
1 inch,2 rows,and 1 1/4 inch 2 rows

i have a 427 big block,with an Edelbrock performer/cam setup,holley 850,hooker headers
and with an 180 degree high flow t'stat,i am Very happy with it.

hope the big block vs small info pops up, ;)
did you try a search?

The 400 HP radiator has a 22" long X 19" tall core with 1" wide tubes.

The 700 HP radiator has a 24" long X 19" tall core with 1" wide tubes.

The original brass/copper 3 core small block radiator cores were 21" wide, and 23" wide for A/C cars. The big blocks had a 23" long 3 core, and the A/C cars went to 4 cores.

I think you would be much better off having a custom built PRC aluminum radiator ordered at http://www.streetrodstuff.com/Products/157/
They're only $348.00 and custom made to any size you want.

Putting horsepower figures on radiator capcity is really a misnomer at best and a marketing ploy at worst.

Heat transfer depends on coolant flow and airflow across the area of raditor so they do not take that in effect per se. You can easily take a stock radiator and turn it into a high performance radiator by simply increasing coolant flow and increasing airflow raising the efficiency!

I second the PRC recommendations and a heavy duty flex fan (Derale of course) to go with if you want a mechanical fan.
