I would like to purchase a new radiator since my has 199,000 on the clock. My motor is modded pretty well with cam pulley drop, springs, bored over a little, proper tune etc, Nothing wrong with the rad, just old and since I have a newly built motor, felt that it is time to replace old one. I do run at the track a lot, so I was wondering if I really needed the expensive zzp one, or if the one at rock auto for 68 bucks will do, or somewhere in between. Also, who in here is still porting TB's. I need this done as well. Thanks!
