So yesterday the radiator springs a small leak. Don't know the history of it as I just bought the car about 2 months ago. May not be original rad, may have been repaired before......so I want a new one to prevent repeat trouble.
My question to all of you is what size (2,3,4 row) should I go with and I want a direct bolt in if possible with existing stock support and shroud. The engine is a 350 crate motor, 350 HP, 700R4 trans.
Is it worth going to an aluminum rad. Any experience with rad sources good or bad would be helpful too.
Thanks

 

I would definitely go aluminum, and go with two 1" rows, not the smaller 2-3 or 4 row 1/2" rows. The two 1" rows will cool better. Aluminum radiators have come so far, and gotten so cheap it's really the best bargain on the market.
Measure your overall width, and height at the tanks, and then check at KMJ Performance. I bought a welded aluminum radiator from them for just over $150, and free shipping.
They have a 19"x31" welded for $129, but it requires a separate trans cooler for your automatic; which is a good idea anyway.
