radiator woes

My 288 radiator was not up to snuff prior to the engine rebuild. I used the guts of a 327 to make it into a 340, thanks to boring out the cylinders. So now the engine gets hot after about 25 minutes of highway driving in 85 degree temp. By hot, it is starting to boil over. I had the 327 radiator, which is thicker than the 288 version, but it had been dry for many years and has dry rotted. The local radiator shop says that they can put a new core in using the old tanks for $495. The thermostat is a new one.

Any suggestions that might be less money? I may just have to bite the bullet and do this, but I thought I'd ask first.
