running hot

lightweight said

So I've been driveing my dart a little bit not much, at idle it will not over heat sitting in the driveway, but when I take it out, for a spin it gets hot and over heats. It never had any problems before I put a 4 inch stroker kit in it. It still has the original radiator the car came out with

Sorry dude, kinda funny!! Yup, your new stroker will need extra cooling! A big block Mopar one will require mods to install and not to mention different hose locations, a PITA. In my Valiant I have a stout 340. I run a original 22" 2 core in my 66 Valiant, I wanted a stock rad so I had it recored with a "high flow efficenicy" core and it works great, even with the stock 4-blade fan it never gets above 180, even in traffic and 95 degree heat! I do run a 4-speed, not sure if that helps cooling but I would think it should. I also run a "Flow-Kooler" water pump, stock 180 thermostat, & 4.10 gears :glasses7:
