340 .40 over with less than 1,000 miles on rebuild
stock pistons
flat tappet cam
initial timing at 12 degrees
edelbrock avs 800 cfm carb
1964 dodge dart
I decided that i would swap out the x heads to eddelbrock 340 heads.
Installation went fine but now i have developed an overheating problem.
At idle it will heat above 210. I have not tried to see where it would stop i just shut it down.
the radiator i had on it cooled just fine would not get past 180. This was a champion 2 row 19"- this is on a 64 dart
Changed to a wider 22inch 3 row champion radiator that i had stored away. no difference
changed to a 160 thermostat . no difference
Using 273 adjustable rockers and double checked to make sure the valves are adjusted properly
coolant looks good . I am using prestone 50/50 premixed
oil looks good Valvoline 10-30 vr same oil i use in all my flat tappet cars
Not sure what else it could be. Did the head gasket blow but did not cause cross contamination of the oil and the coolant?
Thanks in advance.
