Choosing a replacement radiator

[John]

Got the Dewitt's installed this weekend. I kept the one they sent- filler neck on top. It cleared the hood although very close. It's a big core, two rows of 1-1/4" tubes. So far I am happy with results but I don't know for sure if I'll get the electric fan assembly or stay with stock fan. It still wanted to creep when idling. I sat for a bit maybe 5-6 minutes and it got to 180. Temps that day were in the mid 80's. The big difference I noticed is it runs right at 160 when driving. I have a 160 degree thermo but rarely did it sit at 160 while driving unless very cool outside. I have no doubt if I did get the electric fans, I'll have no more temp issue's. After sitting and letting the temp get to 180, within a minute of moving again, temps came right down telling me with the right CFM of air being moved through the radiator it can easily handle the heat.
