I just found out that our radiators are plastic.! That sux!. I feel if u by a performance car u should at least get a performace radiator. damn. Anyway i have a 347 stroker kit in my gt and i notice when i drive for long periods of time on the weekends.(i only drive it on weekends), it slowly tends to lean to the hotter side. i jsut had the motor built and everything is new, oil pump, hoses, power streering pump, water pump, block, rings, almost everyting except athe radiator. I've heard that such a large stroker kit in a daily driver without a better radiator will cause such cooling problems. anybody else have these kinds of problems or comments please feel free to share the wealth. Oh yea, if anybody knows where to get a aftermarket radiator kinda CHEap, damn there expensive, plz share the info. Thanks Guys.!
