Hey guys - i have a newly rebuilt 383, forged pistons - with a vortech s-trim@10psi, the cooling system is a stewart water pump, and a fluidyne 2 core aluminum radiator. My problem is the goddamn car still runs hotter than it should (240ish, no AC..), any ideas? any help would be greatly appreciated as this issue is driving me crazy.

 

More info please. When does it run this hot? What mixture coolant/water are you using? What stat? What kind of fans? What kind of quality is that radiator?

 

Yup. Need mo info.
Is your front skirt (air deflector) for the radiator still connected?

 

Its a fluidyne 2 core aluminum - Yes, the front air deflector is still there, im going to end up getting a new one cause the old one is semi flexible. I found the cooling issue though - bad relay.. grr. she is now running happily at 220. the next issue is a gremlin that keeps toasting TFI coils.

 

wow 220?
If the stock temp gauge can be trusted i run 184 as long as i'm moving. i have a new 195 stat in my car.

 

yeah.. this is in 113 degree heat, at night when its about 90 out - im running about 184-190.. (or so the stock guage says)
