My 87 T/A has a single core radiator with the wide (an inch or so) core that is about as wide as an older 2 core. It was new when I got the car and I have only put 500 or so miles on the car since. I'd rather not replace it, but I am wondering if this is a suitable radiator for use with a performance engine(300 net HP). I haven't had the car out in the summer yet, so I do not know how it will react in the hot weather. It is just a weekend cruiser (once or twice to the track per year).

Any suggestions?

 

i would think you will be fine, a 180 or 170 stat with a good eletric fan should keep you plenty cool.

 

I forgot to mention that I modified the intake to a 4 point cooling system too, and bought the addapter to samich between the stat and intake. (routes coolant from back of heads to front of engine under the stat)

 

The stock one row alum. radiator in the 85(?) - 92 third gens works great. 300hp = no problem. Just gotta make sure fans & rest of cooling system are up to par.
