Sorry -worked late
here is info
stock Iron 346 heads. had 3angle valve job
Mild 440,.040 over, RPM intake,Comp XE268 cam,
KB Hyper pistons . Mancini alumin water pump housing, Mopar hemi water pump,stock crank,
71 Mopar 3core 26"radiator, stock shroud,Mopar clutch fan. 180 thermostat,
dynod at just about 400 HP & 500 torque.

aftermarket cheap temp gauge could be off.
that is what I have been thinking.
Since radiator never pukes out.
I dont really want to go with aluminum rad or electric fans if I dont have too.

does drop to 199 -200 when moving but starts creeping when in traffic.
i was thinking of just letting it go and see if it over heats or not\I also take off out of traffic before is gets over 210 or higher.

what do you think?
