Need a new radiator. Would like an aluminum 3 row, but Be Cool's are $542. Anyone know where I can find one for an 89 350 IROC w/ auto trans for alot cheaper? My other option is a new stock one for around $150, but I'd like an alum. one.

 

Well autozone sells new 3 core brass/copper ones for 120$ Ive had mine for sevral years now with no cooling problems.

check out performanceradiator.com. I just bought a new 3 row aluminum radiator from there for $120. I don't know what the retail is, but they'll bargain with you a bit. Also get a cap from them, my stock cap didn't work.

 

I got an aluminum one thats suppost to be the same as a 3 core for $117 at checker. But i had to re use my old cap

 

Get a Griffin 3 core aluminum, $180, works great, keeps my car running 170* on the highway.
