Hi all, I've replaced the belts and hoses on 6144, but am still having some overheating issues. I have purchased the correct RS 333-180 thermostat and bypass restrictor plate from Marlin Jack (Thank you MJ!) from the advice I have gotten here (thank you all - especially George P. and John B.). My next steps most likely will be to change out the water pump for the Flow Kooler #1648, add the SACC billet pulley and install the thermostat. I wasn't sure if I was going to change the radiator, but upon further inspection I don't like the look of the top nipple at all - it's got a nasty bulge as you can hopefully see in the picture. I would rather go with a copper core radiator and am considering the Hall radiator. The car has been fitted previously with Flex-a-Lite sucker fans which still work (although wired directly to the ignition, another fix needed). I have measured the distance out from the back of the radiator to the 90 degree bend (inside) of the nipple and it appears to be 3 1/4- 3 1/2 inches. Is this normal? Will the Hall have the same amount of clearance? When the radiator was previously out was the nipple extended to allow for the fans? Should I just ditch the current fans and go with the Mirriah pushers? What do you think?
